摘要

This paper reports the results of the study on the performance of low-cost adsorbent such as granular activated charcoal (GAC) and surface modified granular activated charcoal with Sodium dodecylbenzenesulfonate (SDBS), Dioctyl sodium sulfosuccinate (DOSS), Sodium dodecyl sulfate (SDS)in removing Cr (VI), Pb (II), Mn (II) and Bi (III) from aqueous media.The continuous tests were conducted at constant flow rates and bed height. The study were carried out by using initial concentration 21.25 mg/l, 30.75 mg/l, 19.77 mg/l, 20.43 mg/l having pH 2, 5, 11.5 and 1 for Cr (VI), Pb (II), Mn (II), Bi (III) metal ions respectively. Among the various surfactant tested to increase the adsorption capacity of GAC, GAC-loaded with SDS effectively removed the toxic metal ions from aqueous media. It was concluded that the GAC-loaded with SDS was an effective low-costadsorbent for the removal of metal ions from aqueous solutions.
