@article{(Open Science Index):https://publications.waset.org/pdf/14626, title = {Pomelo Peel: Agricultural Waste for Biosorption of Cadmium Ions from Aqueous Solutions}, author = {Wanna Saikaew and Pairat Kaewsarn and Wuthikorn Saikaew}, country = {}, institution = {}, abstract = {The ability of pomelo peel, a natural biosorbent, to remove Cd(II) ions from aqueous solution by biosorption was investigated. The experiments were carried out by batch method at 25 °C. The influence of solution pH, initial cadmium ion concentrations and contact times were evaluated. Cadmium ion removal increased significantly as the pH of the solution increased from pH 1 to pH 5. At pH 5, the cadmium ion removal reached a maximum value. The equilibrium process was described well by the Langmuir isotherm model, with a maximum biosorption capacity of 21.83 mg/g. The biosorption was relatively quick, (approx. 20 min). Biosorption kinetics followed a pseudo-second-order model. The result showed that pomelo peel was effective as a biosorbent for removing cadmium ions from aqueous solution. It is a low cost material that shows potential to be applied in wastewater technology for remediation of heavy metal contamination. }, journal = {International Journal of Chemical and Molecular Engineering}, volume = {3}, number = {8}, year = {2009}, pages = {393 - 397}, ee = {https://publications.waset.org/pdf/14626}, url = {https://publications.waset.org/vol/32}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 32, 2009}, }
