Date of Publication :9th October 2021

Abstract: This study investigates the use of chemically activated Pumpkin (Cucurbita) peels impregnated with H3PO4 (APP) for toxic chromium removal from aqueous solutions. The adsorption processes were carried out through batch method at pH ranges from 2-10 and adsorbent APP dosage of 1-6 g/L. The optimum operating conditions were achieved at pH 2 and time of contact 120 min attaining the highest metal intake at 3g of the adsorbent per 1L of the aqueous solution having total chromium removal of 89%. The adsorption kinetics follows pseudo 2nd order model with a Chi square value of 0.132. Both the Freundlich and Langmuir were applied to describe the experimental data and it fitted well with both the isotherms with a correlation coefficients of 0.97 and 0.99 and a Chi square (2) values of 0.001 and 0.01 respectively.
