    Abstract: The biosorption data of trivalent chromium by <I>Streptomyces rimosus</I> has been used for kinetic studies based on fractional power, Elovich, pseudo-first order and pseudo-second order rate expressions. The time-dependent Cr (III) biosorption data were well-described by pseudo-second-order kinetic model. The intraparticle diffusion is not the rate-limiting step for the whole reaction. The Temkin, Freundlich, Dubinin-Radushkevich and Langmuir biosorption models were used for the mathematical description of the biosorption equilibrium of Cr (III) ions to <I>S. rimosus</I>. It was found that the biosorption equilibrium data fitted well to the Langmuir.
