Adsorptive removal of Cd ions using dolochar at an industrial-scale process optimization by response surface methodology.

In this work, performance of laboratory-synthesized dolochar has been investigated for adsorption of Cd ions in a large-scale process with the application of Aspen Adsorption. Moreover, the optimum values of the operating parameters (namely, flow rate, bed height, and inlet metal ion concentration) that would result into maximum amount of cadmium ion adsorption (high exhaustion capacity) in minimum time (less exhaustion time) for a fixed mass of dolochar have been calculated via the application of response surface methodology. It was found that, at optimum values of bed height (3.
