- The kinetics of aluminium(M) and chromium(M) adsorption in an adsorbent prepared by immobilization of Chaetoceros calcitrans biomass on silica ge has been investigated. The functional groups which were probable involved in the adsorption processes also identifed. Experimentally, the adsorption was conducted by coloumn and batch method. In this work atomic adsorotion spectrophotomettic techniques was applied indirectly to determine the of the metal ion adsorpted, and infra red spectroscopic technique was used for the identification of functional groups present in the adsorbent. The study included two parts of experiment, i.e. 1) the determination Of rate of adsorptionf and 2) the determination of capacity and energy of adsorption. 1.877 kcaUm le for Cr (III). It was concluded that the adsorption of Al(M) and Cr(M) on Chaetoceros calcitrans immobilized and free Chaetoceros calcitrans adsorbents, may be Key worod mmobilized, Chemical adsorption, functional groups
