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
In this study, CuII 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 CuII ions on Z. ramigera immobilized on Ca-alginate was calculated. The Péclet 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.
