Abstract:
The application of an agro-based bio sorbent [water melon seed powder (WSP)] in the sorption of copper (II) ions in aqueous solution were established. The sorbent (WSP) was characterized for moisture content (3.04%), point of zero charge (6.00), loss on ignition (65.8), specific gravity (2.13) and FTIR before and after sorption. Henry's one parameter adsorption model with the constant (KHe) of 202.03, regression (R2) of 0.97 was adopted in studying the process favorably. The zero point of charge (ZPC) declared the bio sorbent to be more active under alkaline (pH = 8) condition or modification. The actual average percent of Cu2+ removal was statistically calculated to be (98.01 ± 0.54) % with 1g/50ml (pH >6).WSP has been a low cost, and environmentally renewable bio sorbent has been ascertained to be potentially active naturally in the removal of metallic pollutants like Cu2+ in solution.
