Abstract

JatrophaCurcas seed coat activated carbon was used as adsorbent for the adsorption of paraquat dichloride (herbicide) from aqueous solution. Paraquat dichloride adsorption spectrum ranges from 0.029 to 3.145 and the maximum absorbance was recorded at 500 nm. The standard calibration curve obeys Beer-Lambert’s Law as the absorbance increases with increase in concentration. The effects of initial concentration was studied and the percentage absorbed ranges from 42.85 % to 84.69 %, the effect of contact time shows that the amount adsorbed decreased as the contact time increases. The effect of pH shows absorbance ranges from 1.173 to 1.906 within a pH range of 2 to 10 and the effect of temperature shows Qe ranges from 0.0086 mg/g to 0.121 mg/g within a temperature range of 35 0C to 55 0C. Isotherm studies indicate an inhibitory effect, promoted by JatrophaCurcas seed coat activated carbon. Overall, the results from this study demonstrated that the JatrophaCurcas seed derived activated carbon can be used as a low-cost adsorbent for the removal of environmental cationic organic pollutants from the environment.
