Abstract
In the present study sugarcane baggase (Saccharum officinarum L.) was studied as a cost effective biosorbent for Pb(II) ions was investigated using batch technique. FTIR analysis of the biosorbent revealed that hydroxyl, carbonyl and carboxyl groups which are involved in the uptake of lead (II) ions. SEM represents porous structure with large surface area. The effects of operational factors including solution pH, biosorbent dose, initial lead (II) ions concentration, contact time and temperature on the biosorption efficiency were studied. The experimental equilibrium biosorption data were fitted by four widely used two-parameters Langmuir, Freundlich, Dubinin-Kaganer-Redushkevich (DKR) and Temkin isotherm equations. Simple kinetic models such as pseudo-first-order, pseudo-second-order, Elovich equation and Weber and Morris intraparticle diffusion rate mixing equation were employed to determine the adsorption mechanism. Thermodynamic studies were also carried out. The results showed that sugarcane baggase (Saccharum officinarum L.) was a low-cost capable sorbent to seize Lead(II) from wastewater
