Title

REMOVAL OF COPPER FROM AQUEOUS SOLUTION USING TRIPLOCHITON SCLEROXYLON SAWDUST: EQUILIBRIUM AND KINETIC STUDIES

Pages

  294-306

Abstract

 Sawdust of Triplochiton Scleroxylon was evaluated as a new biosorbent of heavy metals. On contacting 100mgL-l COPPER (II) solutions with 20 g L-1 SAWDUST, during shake flask contact time of 45 min, the metal removal was noted to be 69%. The influence of pH, sorbent dose, concentration, temperature, and contact time on the SORPTION of Cu (II) on SAWDUST has been studied by batch process. The optimum conditions of SORPTION were found to be: contact time of 45 min, pH and temperature 4.0 and 40oC respectively. The SORPTION KINETICS was found to follow pseudo-second-order model. The SORPTION data perfectly fit the linear Langmuir isotherm model with 0.99 regression coefficient (R2) and 0.66 average percentage errors (e%). The fit on Freundlich adSORPTION isotherm model was acceptable but not as good. Calculated thermodynamic parameters such as DHo, DSo and DGo indicated spontaneous and exothermic nature of the process. The study points out the potential use of SAWDUST; at present has no commercial value, for the treatment of wastewaters contaminated with heavy metals.
