Competitive biosorption of pb (ii) and ni (ii) onto
newly synthesized spongy thiourea modified spentgrated
coconut / Muhammad Ikram Mohd Apdi@normi.

Abstract
The waste from spent-grated coconut was used and modified as new biosorbent to
investigate the biosorption of Pb (ii) and Ni (ii). Initially, SGC was treated with
hexane and followed by thiourea to form TSGC. This biosorbent were characterized
by FTIR, pHslurry and pHzpc. The experimental equilibrium adsorption data were
analyzed by two model and two isotherm- Pseudo-first order model, Pseudo-second
order model, Langmuir isotherm and Freundlich isotherm. Among these, only
Freundlich isotherm was fitted with both Pb (lI) and Ni (II) as it correlation
coefficients (R2) close to to unity. For Pseudo-first order model, only Pb (II) ions was
fit with it. For Pseudo-second order model, only Ni (ii) was fit it.
