Poly(methacrylic acid)-grafted chitosan microspheres via surface-initiated ATRP for enhanced removal of Cd(II) ions from aqueous solution

Removal of cadmium from aqueous solution using low molecular weight chitosan derivative

“…The main sources of cadmium discharge into the environment by waste streams are electroplating, smelting and alloy manufacturing, pigments, plastics, battery mining and refining processes (Benguella & Benaissa, 2002). Cd(II) has been well documented for its harmful effect on living systems (Huang et al, 2013). Cd(II) is known to lead into bone lesions, hypertension, renal disturbances, cancer and lung insufficiency in humans (Sharma, 1995).…”

Rapid removal of cadmium ions using green-synthesized Fe3O4 nanoparticles capped with diethyl-4-(4 amino-5-mercapto-4H-1,2,4-triazol-3-yl)phenyl phosphonate

“…21 Since the performance of an adsorptive separation technique is directly dependent on the quality and effectiveness of the adsorbent, various noble adsorbents (zeolites, 22 activated carbon, 23 chitosan, 24 clay minerals, 25 tea waste, 26 lignocellulose, 27 and functionalized polymers 28 ) have been developed for commercial applications. 21 Since the performance of an adsorptive separation technique is directly dependent on the quality and effectiveness of the adsorbent, various noble adsorbents (zeolites, 22 activated carbon, 23 chitosan, 24 clay minerals, 25 tea waste, 26 lignocellulose, 27 and functionalized polymers 28 ) have been developed for commercial applications.…”

The enhanced removal of cationic dyes in binary system using novel copolymers with two kinds of acidic groups

“…Hydrogels, three-dimensional polymeric structures, have ability to uptake and retain large amount of liquid and swell several hundred times of their original weight allowing free diffusion of solute molecules like dye, organic or metal species [14]. In recent years, poly(methacrylic acid) (PMAA) based hydrogels have been increasingly investigated for removal of metal ions and organic compounds from wastewater [15][16][17][18][19][20], while there are only few studies of PMAA hydrogels and their modifications employed in removal of dyes from wastewater. Poly(methacrylic acid) hydrogels have COOH functionalities and without neutralization exhibit low uptake of aqueous solutions.…”
