Recent research on metal biosorption has been elucidating its mechanisms and principles. For effective metal removal/recovery the process design has to be optimised for every type of application. That is most effectively done based on computer simulations utilizing mathematical models of the process. Some brief points of modelling methodology are summarized here. 1. Equilibrium Modeling Biosorption has been studied with simplified sorption systems usually containing one heavy metal. This is quite appropriate simplification required for effective studies. Yu and Neretnieks1 thoroughly reviewed model isotherms for single-component adsorption. Table 1 summarizes some of the most frequently applied simple sorption isotherm models.
