Adsorption of Lead from Aqueous Solution by Hybrid Precursor from Rice Husk
M. K. Bhatnagar, Awanish Patel
Abstract: A carbon adsorbent derived from rice husk by nitric acid treatment was used for the removal of Pb (II) from aqueous solution. Sorption of metal ion has been studied as a function of contact time, temperature, pH of the solution and metal ion concentration. These factors have remarkable positive effect on sorption process. The adsorption data of RHHP at different initial concentration was fitted to Freundlich & Langumir adsorption isotherms and monolayer sorption capacity determined was 72.04 (pH 6.0 temperature200c). Thermodynamic Parameter indicated that the sorption is exothermic, spontaneous with a greater affinity of metal species for the adsorbent.
