AB  - Nanoparticles of TiO2 are suitable for many catalytic and photocatalytic applications due to their extraordinary properties such as superhydrophobicity, semiconductivity, electron-rich, and environmental compatibility. The main crystalline phases of TiO2, anatase, and rutile possess different crystal structures, crystallinity, crystalline sizes, and specific surface areas, and these characteristics directly affect the catalytic performance of TiO2. In the present study, domestic carbon material enhanced with TiO2 nanoparticles was synthesized and used for the construction of a modified carbon paste electrode. The electrocatalytic activity of the modified electrodes was investigated depending on the TiO2 crystalline phases in the electrode material. Furthermore, the obtained working electrode was utilized for triclosan detection. Under optimized experimental conditions, the developed electrode showed a submicromolar triclosan detection limit of 0.07 µM and a wide linear range of 0.1 to 15 µM. The relative standard deviations for repeatability and reproducibility were lower than 4.1%, and with satisfactory selectivity, the proposed system was successfully applied to triclosan monitoring in groundwater. All these results confirm that the sustainable production of new and domestically prepared materials is of great benefit in the field of electrocatalysis and that the morphology of such produced materials is strongly related to their catalytic properties.

AB  - This chapter summarizes the reactivity, mechanism and toxicity assessment of pesticides and pharmaceuticals by chlorine dioxide (ClO2). ClO2 has been successfully employed as disinfectant in water treatment systems due to its antibacterial and antiviral characteristics. Also, ClO2
can be used as an alternative to chlorine, compared with which, it effectively reduces the amount of chlorinated products. As a powerful oxidant, ClO2 can remove effectively many organic and inorganic pollutants from water. Anthropogenic influences on groundwater (mining, industrial, agricultural and urbanization activities, and/or climate change) can affect water quality by production of different contaminants. The quality of surface water is critical because of the importance of raw water quality for all forms of life. Considering the increasing application
of ClO2 in water treatment, it is very important to investigate the reactions of ClO2 with the most extensively consumed pharmaceutical drugs and pesticides, which are regularly detected in surface water. Oxidative degradation via ClO2 of pharmaceutical contaminants and pesticides from water solutions is presented. Pollutants on which ClO2 has high or low degradation efficiency are highlighted. The recent developments on the effects of organic substances on pollutant degradation in surface water are addressed. Future trends in pollution degradation using ClO2 are also discussed.

AB  - Chlorine dioxide has been reported as very
efficiently removing pesticides and other organic compounds
from water matrixes. Due to pesticide toxicity
and potential toxicity of their degradation products, it is
important to monitor these compounds as environmental
pollutants in ground and surface waters. Evaluating
the effects of chlorine dioxide treatment is necessary,
and toxicity studies are used to ascertain the severity of
effects of intermediates due to incomplete degradation
of the parent compounds. In this paper, for the first time,
chlorine dioxide is applied and evaluated for the removal
of chloroacetamide herbicides (pethoxamid and
metazachlor) from waters (deionized water and Sava
River water). The degradation degree of herbicides
was measured by high-performance liquid chromatography,
the main degradation products were identified
using gas chromatography with a triple quadrupole mass
detector, and the degree of mineralization was
monitored by total organic carbon analysis. Four and
two degradation products were identified after
pethoxamid and metazachlor degradation, respectively.
Total organic carbon analysis showed mineralization
occurred, but it was incomplete. The mineralization
and the characteristics of the degradation products obtained
were tested using Daphnia magna and showed
lower toxicity than the parent herbicides. The advantage
of the applied treatment was a very high degradation
percentage for pethoxamid removal from deionized water
and Sava River water (100% and 97%, respectively),
with higher mineralization efficiency (65%) than
metazachlor. Slightly lower degradation efficiency in
the Sava River water was due to chlorine dioxide oxidizing
the herbicides and dissolved organic matter
simultaneously

AB  - Bentazone degradation efficiency and mineralization in water solutions using chlorine dioxide
treatment were evaluated. Double distilled water and a river water sample spiked with bentazone
were studied and compared after chlorine dioxide treatment. Degradation efficiency was determined
using high-performance liquid chromatography (HPLC). Daphnia magna toxicity testing and
total organic carbon (TOC) analysis were used to ascertain the toxicity of the degraded solutions
and mineralization degree. Bentazone degradation products were identified using gas chromatography
with a triple quadrupole mass detector (GC-MS-MS). A simple mechanistic scheme for oxidative
degradation of bentazone was proposed based on the degradation products that were
identified. Decrease in D. magna mortality, high degradation efficiency and partial bentazone mineralization
were achieved by waters containing bentazone degradation products, which indicate
the formation of less toxic compounds than the parent bentazone and effective removal of bentazone
from the waters. Bentazone degraded into four main degradation products. Humic acid from
Sava River water influenced bentazone degradation, resulting in a lower degradation efficiency in
this matrix (about 10% lower than in distilled water). Chlorine dioxide treatment of water to
degrade bentazone is efficient and offers a novel approach in the development of new technology
for removal of this herbicide from contaminated water.

AB  - Chlorine dioxide (ClO2) degradation of the organophosphorus pesticides azamethiphos (AZA) and dimethoate (DM) (10
mg/L) in deionized water and in Sava River water was investigated for the first time. Pesticide degradation was studied
in terms of ClO2 level (5 and 10 mg/L), degradation duration (0.5, 1, 2, 3, 6, and 24 h), pH (3.00, 7.00, and 9.00), and
under light/dark conditions in deionized water. Degradation was monitored using high-performance liquid chromatography.
Gas chromatography coupled with triple quadrupole mass detector was used to identify degradation products of
pesticides. Total organic carbon was measured to determine the extent of mineralization after pesticide degradation. Real
river water was used under recommended conditions to study the influence of organic matter on pesticide degradation.
High degradation efficiency (88–100% for AZA and 85–98% for DM) was achieved in deionized water under various
conditions, proving the flexibility of ClO2 degradation for the examined organophosphorus pesticides. In Sava River
water, however, extended treatment duration achieved lower degradation efficiency, so ClO2 oxidized both the pesticides
and dissolved organic matter in parallel. After degradation, AZA produced four identified products (6-
chlorooxazolo[4,5-b]pyridin-2(3H)-one; O,O,S-trimethyl phosphorothioate; 6-chloro-3-(hydroxymethyl)oxazolo[4,5-
b]pyridin-2(3H)-one; O,O-dimethyl S-hydrogen phosphorothioate) and DM produced three (O,O-dimethyl
S-(2-(methylamino)-2-oxoethyl) phosphorothioate; e.g., omethoate; S-(2-(methylamino)-2-oxoethyl) O,O-dihydrogen
phosphorothioate; O,O,S-trimethyl phosphorodithioate). Simple pesticide degradation mechanisms were deduced.
Daphnia magna toxicity tests showed degradation products were less toxic than parent compounds. These results
contribute to our understanding of the multiple influences that organophosphorus pesticides and their degradation
products have on environmental ecosystems and to improving pesticide removal processes from water.
