Waste Cotton and Cotton/Polyester Yarns as Adsorbents for Removal of Lead and Chromium from Wastewater
(Journal of Natural Fibers, 2022)
The possibility of using waste cotton and cotton/polyester yarns to remove lead and chromium ions from polluted water was investigated in this work. Structural, morphological, and adsorption properties of yarns were ...
The Application of a Natural Zeolite for Acid Mine Drainage Purification
(Japan Inst Metals & Materials, Sendai, 2015)
A natural zeolite from Serbia was employed for the removal of heavy metals from acid mine drainage (AMD) generated in the area of copper mine. The efficiency of the natural zeolite samples was tested on AMD that contained ...
Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
ORGANIC DYES ADSORPTION ON CARBON ADSORBENTS DERIVED FROM WASTE COTTON AND COTTON/POLYESTER YARN / ADSORPCIJA ORGANSKIH BOJA NA UGLJENIČNIM ADSORBENTIMA DOBIJENIM OD OTPADNOG PREDIVA PAMUKA I PAMUK/POLIESTRA
(Belgrade : Union of Engineers and Textile Technicians of Serbia, 2023)
In an attempt to reuse fibrous textile waste, and at the same time to reduce its quantity, waste cotton-based yarn was used as a cheap and sustainable precursor for carbon adsorbents production. Cotton and cotton/polyester ...
Ispitivanje adsorpcionih svojstava ilovače za uklanjanje jona olova i arsena iz vodenih rastvora
(Akademija tehničkih strukovnih studija Beograd, 2021)
Olovo i arsen predstavljaju značajnu grupu neorganskih polutanata koji su prisutni u
životnoj sredini, pre svega u vodenim sistemima, pa je njihovo uklanjanje veliki tehničkotehnološki izazov. Zbog toga se sve više pažnje ...
