摘要：The removal of arsenic ions from aqueous streams using the scales of Atlantic Cod species (Gadus morhua) involves adsorption and possible precipitation of its constituents, and is dependent on the number of available surface excess sites per mass unit of the bio‐adsorbent. In modelling the adsorption behaviour of metal ions, the numerical code based on surface excess theory was applied using a two‐dimensional mass transport model for determination of breakthrough characteristics in dynamic packed bed columns. Numerical simulation data, using surface excess theory, demonstrate a reasonably close agreement with experimental results from dynamic column tests. Parameters such as porosity, selectivity, flow rate, and adsorption coefficient contribute significantly to the variation in breakthrough time intervals associated with dynamic packed bed adsorption columns.
