Abstract :
Water pollution is one of the most prevalent
problems affecting people throughout the world, while
adsorption is the most widely used method to remove the
contaminants from water. In this present study, a series
of eco-friendly Sodium salt of carboxymethyl celluloseStarch-Gelatin hydrogels were prepared using Citric
acid as the chemical crosslinker by changing
biopolymers and crosslinker percentages.
Characteristics of the hydrogels were investigated by
swelling test and Fourier Transform Infrared (FTIR).
Swelling behavior was tested in cold and hot water,
acids, alkalies salt water etc. Water uptake by the
hydrogel increased when starch concentration increased
but decreased when gelatin and crosslinker
concentration increased. Further, the hydrogel was
evaluated as a bio adsorbent for the removal of dyes,
namely Crystal violet and Rhodamine B from water.
Maximum dye adsorption was seen for crystal violet.
Metal adsorption was also studied using copper sulphate
solution.
