摘要：

Effect of treatment of C-cloth with sodium hydroxide on the adsorption capacity for the adsorption of several metal cations was studied. The concentration of ions in the solution was monitored using atomic absorption spectrometer. The adsorption isotherm data for the cations were derived at 25 C and treated according to Langmuir and Freundlich models. It was found that for most of the investigated cations Langmuir model was more successful. Adsorption capacities were determined from Langmuir isotherms. Treatment of the adsorbent with NaOH increased the adsorption capacity for the adsorption of all of the investigation ions. (c) 2007 Elsevier B.V. All rights reserved.
