AB  - Population growth, the development of agriculture, industry, and mining, caused the creation of an increasing amount of  wastewater. Due to the discharge of wastewater, without prior treatment, the quality of water resources is impaired.  Polluting substances, such as pesticides, have a negative impact on human health and the environment. Heavy pollution  of both surface and underground water is one of the biggest problems associated with the use of pesticides. They reach  human organisms indirectly via agricultural products. Most pesticides are more or less toxic, some of them are highly  soluble in water. In recent years, special attention has been paid to the development of methods for the treatment of  wastewater contaminated with pesticide residues, in order to partially reduce or eliminate their further impact on humans,  plants, and the environment. Among many processes, the photocatalytic degradation process has proven to be a very  effective process for the removal of pesticides from wastewater. Photocatalytic degradation implies the breakdown of  various types of toxic organic substances into simpler molecules, such as ions, water, etc.  In this paper, the photocatalytic degradation of the pesticide mesotrione (MS) using ZnO photocatalyst is presented. The  degradation of the pesticide compound was studied using Shimadzu 1800 analytical UV-VIS spectroscopy. As a  replacement for UVC radiation, a solar-imitated irradiation Ultra Vitalux (UV) lamp (300W) was used. Degradation  kinetics follows pseudo-first order. After 240 minutes, the MS was completely degraded.

AB  - In the last decades, the rapid development of industrial and agricultural activity caused the release of different organic/or nonorganic pollutants in water, earth, and air which lead to a threat to human health and the ecological environment. These pollutants contain toxic heavy metals, organic dyes, pesticides, pharmaceutics, and others (Aboua et al., 2015). Organic dyes are visible pollutants used as coloring agents in, textiles, plastics, paper, food industries, etc. For their removal from wastewater, eco-friendly treatment is needed. Among many process purification, the process of adsorption proved to be an effective method for removing pollutants that are present in water, such as pesticides, dyes, and heavy metal ions. Due to the specific properties of polluting substances, the goal is to develop a cheap, efficient, environmentally friendly material. Among them, cotton-based materials can be obtained from various natural sources and can be employed as inexpensive adsorbents. Their adsorption capacities for pollutants can be related to chemical treatment. In general, chemically modified cellulose exhibits higher adsorption capacities for various aquatic pollutants than their unmodified forms. In this aim, oxidized cotton fabric was used in this work, which was chemically modified with citric acid and ethyl lysinate, respectively. In order to activate the surface of the fabric for chemical modification and increase absorption ability, carboxyl and aldehyde functional groups were introduced using hydrogen peroxide. Then the oxidized cotton fabric was cross-linked with citric acid and ethyl lysinate (Co-CA-Et-Lys) using diisopropylcarboimide to promote ester and amide groups formation. The structure of obtained material was analyzed by using the ATR-FTIR technique. The resulting modified fabric proved to be a good adsorbent for the removal of cationic dyes malachite green (MG) and methylene blue (MB). Its adsorption behavior with respect to the pH, adsorption time, and initial concentration was investigated. Based on the obtained results, it was concluded that the adsorption equilibrium was reached after 1 h for both Malachite Green (MG) and Methylene Blue (MB). Adsorption kinetics data were satisfactorily fitted with the pseudo-second-order rate model (PSO), and adsorption data were best fitted using Langmuir model. The Langmuir maximum adsorption capacities for Co-CA-Et-Lys cross-linked fabric showed a maximum of 168.4 mg/g and 124.9 mg/g for MG and MB, respectively. Compared to other adsorbents based on natural materials, oxidized cotton fabric showed much better sorption properties.

AB  - There is a long process to transform bauxite, a critical raw material, into a substance with the required properties of cast aluminum alloys for use in electro automotive parts. Thanks to its unique properties, aluminum has become the material of choice for clean technology manufacturers in applications such as use in the automotive industry, renewable energy, batteries, electrical systems, resource-saving packaging, energy efficient buildings and clean mobility. Restructuring of the economy, the oil crisis, air pollution and global warming are some of the factors that have moved the automotive industry towards electrification since the beginning of the 21st century. This paper aims to highlight the required properties of cast aluminum alloys applied to the production of electro automotive parts, such as their mechanical and thermophysical properties, dimensional stability, corrosion resistance, electromagnetic compatibility and crashworthiness. Furthermore, this paper discusses which of the cast aluminum–silicon alloys, as well as the heat treatments and casting processes, are most suitable.
