The removal of chromium from aqueous solution in a well-stirred batch reactor by sorption on Aeromonas caviae biomass particles, isolated from potable groundwater supplies, was investigated. Equilibrium and kinetic experiments were performed at various initial bulk concentrations, biomass loads, and temperatures, with promising results. It was seen that the sorption capacity is appreciable for most experimental conditions, so the biomass can be considered as a suitable biosorbent for applications. Moreover, the sorption rate of the metal ions was found to be particularly sensitive to both the initial bulk concentration and the biomass load. A detailed analysis was conducted examining several diffusion (external and intraparticle) kinetic models to identify a suitable rate expression, and interesting conclusions were reached. In this effort, information from SEM analyses and certain desorption runs was also incorporated
