INVESTIGATIONS ON CEPHALOSPORIN-C ADSORPTION-KINETICS AND EQUILIBRIA

The kinetics and equilibria of cephalosporin C adsorption on different commercial adsorbents were investigated. Adsorption isotherms could be analysed according to the Brunauer, Emmett and Teller theory. For the interpretation of adsorption kinetics it was necessary to develop a more complex model comprising both a rapid and a slower step. An integrated approach combining kinetics and equilibria allowed for simulation of the experimental data and can be used as a basis for predicting technical approaches such as fluidized-bed technology. © 1990 Springer-Verlag.
