dc.description.abstractMelon husk, a readily available agricultural waste product was used as a low-cost potential adsorbent to remove cadmium and from industrial effluents. Adsorption studies were carried out on two different activated melon husks as afimetion of parameters such as contact lime, adsorbent dosage and adsorbate concentration. Cadmium removal was found to be dependent on the three parameters with maximum removal attained at 50 min with l.Og for sodium hydroxide (NaOH) activated melon husks and at 70 min with 0.6 g for sulphuric acid (H7SO4) activated melon husk. The metal was mostly removed at low adsorbate concentration. Adsorption isotherms correlated well with both Langmuir and Freundlich isotherm models and their R2 values are 1 for both. Experimental data were also evaluated to find out kinetic characteristics of the adsorption process. Adsorption process for the target heavy metal ion was found to follow pseudo-second order adsorption kinetics. While their? values are 0.7979 and 0.8486 for both H2SO4 and NaOH modified melon husks. The r values showed that both H2SO4 and NaOH modified melon husks are efficient adsorbents with NaOH more efficient. Activated melon husk, a readily available adsorbent was found to be efficient in the uptake of Cd(ll) ions in industrial effluents, thus, making it an excellent alternative for the removal of heavy metals from water and waste wateren_US
