Abstract :

Water is one of the most important chemicals and vital fluids without which living things are impossible. Today, many factors cause environmental water pollution that in this article, we try to absorb nitrophenol derivatives from contaminated water by poly co-hydrogel (vinylpyrrolidone-co-allylamine hydrochloride). Today, many factors cause pollution of environmental waters. In this article, we tried to absorb nanonitrophenol derivatives from contaminated water by co-hydrogel (vinyl pyrrolidone-co-allylamine hydrochloride). In this project, free radical polymerization at 70°C for 5 hours and 20 minutes using A.I.B.N as the initiator of N and N 'methylene base acrylamide as a crosslinking agent were prepared. then, the uptake of nitrophenol toxin from contaminated water by hydrogels was investigated. In this work, 5 to 20 ppm of nitrophenol and the amount of 0.02, 0.05, 0.1 g of hydrogel in different monomeric ratios (1:1, 1: 0.5, 1:2 The amount of adsorption was measured, which increased with increasing the amount of hydrogel and also increasing the concentration of nitrophenol.
