Title: In air synthesis of Psy-cl-poly(AAm) network and its application in water-absorption from oil-water emulsions
Abstract: In this current investigation psyllium has been functionalized with acrylamide in the presence of potassium persulphate (KPS)-hexamethylene tetramine (HMTA) as an initiator-crosslinker system.After the initial optimization of different reaction parameters the resultant hydrogel was used for the absorption of water from different water-oil emulsions as a function of time, temperature, pH and NaCl concentration.4216% of water absorption with 4.279•10 -2 mol•l -1 HMTA concentration has been observed.
