| Abstract |
Experiments were carried out to study the adsorption of silver from a cyanide solution on activated carbon. The tests were conducted on a variation of inital silver concentration (Co), carbon amount(W). mixing speed, particle size and adsorption temperature. The experimental data were found to fit Freundlich adsorption isotherm as well as Langmuir adsorption isotherm. It was found that the loading carpacity of the carbon was 20 ㎎ Ag/g carbon. The isosteric heat of adsorption was found to be 1.48 ㎉/g-mole, indicating physical adsorption. The experimental results were finally compared with the theoretical results obtained by the mathematical modeling equation. A correlation equation was also developed to predict the late of apparent adsorption. Good agreements were obtained. |
