Abstract
Starch extracted from Sorghum bicolor grains was gelatinized and grafted with acrylic acid (AA) and acrylamide (AAm) using potassium persulphate(KPS) as an initiator. Different parameters of grafting reaction such as reaction time, temperature, initiator concentration, and starch to monomers ratio were optimized. Material thus produced was dried, grounded and characterized using FT-IR and SEM. Grafted starch products were saponified with 0.1 N NaOH solution followed by neutralization and drying. Maximum absorbency of 225.5 gg-1 in normal water was obtained, qualifying it as super absorbent product (SAP).
