Description 643-655
In present scenario, anthropogenic activities have degraded the quality of water bodies to an unbearable level. Discharge
of untreated industrial and other effluents have made the water unconsumable. Present work is an attempt to fabricate new
stimuli responsive adsorbent based on natural exudate gum sterculia, an indigenous natural gum for uptake of a cationic dye
malachite green. Magnetic field responsive terculia gum–graft-poly(n-isopropylacrylamide-co-acrylamide) nanocomposite
have been prepared and assessed it as adsorbents for enrichment of malachite green from aqueous solution. The
nanocomposite is characterized by FTIR, TG-DTA, VSM and swelling studies. The VSM results have shown is
superparamagnetic behaviour of nanocomposite with saturation magnetization of 1.5065 emu/g. The adsorption follows
Temkin isotherm and results indicate maximum adsorption capacity of 19.977 (98.78%) malachite green. The desorption
studies demonstrates excellent recovery ability of nanocomposite. The adsorption study confirms the prospective
applications of polysaccharide based magnetic hydrogel for the fruitful and greener disposal of cationic dyes.
