Scientific aspects and technological usage of biosorption processes are extremely actual now. The development of an effective technology demands complex approaches and the joint use of the theoretical and practical aspects. The biosorption characteristics are very much depend of the degraded organic substance properties, the adsorbent nature and structure and the involved microorganisms properties .It was shown polymeric adsorbents are very perspective materials for biosorption processes.

A mathematical model described the biosorption process onto porous polymeric sorbents is proposed. This model summarized the adsorption equations in a fixed bed takes into consideration a biochemical process. The initial equations systems united an equation for mass balance in liquid and solid phase, sorption isotherm, an equation for the velocity of the biomass growth and the corresponding initial and boundary condotopns. The methodology for parameters determination characterized a biological process with the combining both theoretical and experimental methods has been worked out. Models which assumed adsorptive and biological degradation as paralleled processes have been developed.

Biosorption processes onto porous polymeric sorbents have been realized for different experimental systems. The best results were obtained for the systems:

Aniline-polysorb 40|100 -P. Putida and

p-aminophenol - polysorb Y-59 -Pseudomonas sp.
