The adsorption of copper(II) by Z. ramigera immobilized on Ca-alginate in packed bed columns: A dynamic approach by stimulus-response technique and evaluation of adsorption data by moment analysis



The adsorption of copper(II) by Z. ramigera immobilized on Ca-alginate in packed bed columns: A dynamic approach by stimulus-response technique and evaluation of adsorption data by moment analysis



Chemical Engineering Journal 65(1): 81-86



In this study, Cu-II adsorption by Z. ramigera immobilized on Ca-alginate was investigated in a packed bed column test circuit using a stimulus-response technique. The mathematical model was described and solved using "parameter estimation by cybernetic moment technique", and the adsorption rate constant of Cu-II ions on Z. ramigera immobilized on Ca-alginate was calculated. The Peclet numbers, which reflect the column flow characteristics in the cases of no diffusion and/or no adsorption, were calculated. The diffusional effects inside the pores of biomass immobilized on Ca-alginate matrices were investigated. The moment technique was used for evaluation of stimulus-response data of heavy metal-biosorbent interactions, to determine the process parameters.
