The Adsorption of Crude Oil From an Aqueous Solution Using a Gum tragacanth Polyacrylic Acid Based Hydrogel

The adsorption of crude oil from aqueous solution was carried out using a Gum tragacanth-acrylic acid based hydrogel. The prepared hydrogel was characterized using TGA/DTA/DTG techniques. Effect of pH, contact time, acrylic acid, and glutaraldehyde concentration for the adsorption of oil from aqueous solution was measured. Maximum crude oil adsorption from synthesized hydrogel occurred at 40% of acrylic acid concentration. The results showed that in case of pH, maximum adsorption occurred at acidic pH followed by alkaline and neutral pH.
