Abstract

Removal of lead metal ion from wastewater using mixed adsorbent (ragi husk powder and borasus flabellifer coir powder) has been carried out in a batch fashion. Various parameters viz., agitation time (0-120 minute), adsorbent dosage (0.05-1.2 g), adsorbent size (100 μm), pH (3-10), concentration (20-100 mg/L) have been studied. The agitation time at equilibrium has been obtained at 50 minute. The maximum removal of lead metal ion in terms of percentage from wastewater has been obtained at pH of 8. It follows second order adsorption kinetics model and also Langmuir and Freundlich isotherm models. The maximum lead metal uptake was 90.91 mg/g at 303 K. The absorbent presently used is available naturally and abundantly in our environment and also biosorption is one of the low cost processes for the removal of lead metal ion from wastewater using mixed adsorbent.
