Organobentonites as adsorbents of complex mixtures of dyes and heavy metals
(Serbian Chemical Society, Division of Analytical Chemistry, 2011)
Untreated textile wastewaters often contain a great diversity of organic and inorganic pollutants (including non-biodegradable substances like dyes, additives, as well as heavy metal cations like Cu2+, Cd2+, Zn 2+, Pb 2+, ...
Analysis of Intrinsic Stochastic Fluctuations of the Time Response of Adsorption-Based Microfluidic Bio/Chemical Sensors: the Case of Bianalyte Mixtures
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Real-time in situ operation of bio/chemical sensors assumes detection of chemical substances or biological specimens in samples of complex composition. Since sensor selectivity cannot be ideal, adsorption of particles other ...
Organobentonite: Characterization and Adsorptive Properties towards Phenol and its Derivatives
(International Institute for the Science of Sintering, Beograd, 2016)
Bentonite from Mecji Do locality in Serbia was modified with hexadecyltrimethylammonium bromide (HDTMA-Br), and the sample was denoted as HDTMA-MD. The characterization of the material included X-Ray diffraction, elemental ...
Copper removal capacity by zeolite: Comparation in a batch and fixed-bed system
(Belgrade, Serbia : University of Belgrade - Faculty of Mining and Geology, 2019)
The increasing levels of industrial wastewater that are released to the environment present a serious threat to human health, living resources, and ecological systems. Zeolites tested for removal of Cu+2 from contaminated ...
The removal of nicotine from aqueous solution by adsorption onto montmorillonite
(Spain : Sociedad Española de Arcillas (SEA)Bari, Italy : Digilabs, 2017)
Wastewaters polluted with nicotine have been classified as toxic and hazardous by European Union Regulations. Using montmorillonite as nicotine adsorbent has several advantage to other methods and/or adsorbents since ...
Analysis of Reversible Adsorption in Cylindrical Micro/Nanofluidic Channels for Analyte Sensing and Sample Dilution Applications
(Beograd : Društvo za ETRAN / Belgrade : ETRAN Society, 2015)
The principle of operation of one class of chemical/biological sensors is based on adsorption of particles of a target substance from a fluid on a surface which can be a wall of a micro/nanochannel. When a channel is used ...
Removal of manganese and iron from groundwater in the presence of hydrogen sulfide and ammonia
(Scientific Research, 2014)
Presence of iron and manganese in water not only affects the organoleptic properties of water, but
also can cause a number of problems in drinking water treatments. Their removal in drinking water
preparation processes ...
Technetium removal from the aqueous solution using zeolites A and Y containing transition metal ions Co2+ and Zn2+
(Dordrecht : Springer, 2018)
The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance ...
