|Title:||Combined effect of carbon dosage and initial adsorbate concentration on the adsorption isotherm of heavy metals on activated carbon||Authors:||Tan, T.C.
|Issue Date:||Oct-1987||Citation:||Tan, T.C.,Teo, W.K. (1987-10). Combined effect of carbon dosage and initial adsorbate concentration on the adsorption isotherm of heavy metals on activated carbon. Water Research 21 (10) : 1183-1188. ScholarBank@NUS Repository.||Abstract:||The adsorption of dissolved chromium and lead ions by powdered activated carbons significantly depends on the pH, initial adsorbate concentration and carbon dosage. Freundlich and Langmuir equations were unable to describe adequately the observed isotherms under the combined influence of both the carbon dosage and initial adsorbate concentration. These equations were modified and the resulting equations were found to correlate well with the experimental equilibrium data. The modified Langmuir equation gave an overall mean ratio of calculated to experimental adsorptive capacity of 1.001 compared with 1.046 given by the modified Freundlich equation for a total of 135 sets of equilibrium data obtained at different carbon dosages and initial adsorbate concentrations.||Source Title:||Water Research||URI:||http://scholarbank.nus.edu.sg/handle/10635/67386||ISSN:||00431354|
