Arsenic removal in an iron oxide-coated fungal biomass column: Analysis of breakthrough curves

Column studies were conducted, using iron oxide-coated Aspergillus niger biomass, to examine the removal of arsenic [As(III) and As(V)] from an aqueous solution. The Thomas and Yan models were examined to predict the breakthrough curves. The Yan Model described the data better (based on the R 2 valu...

Description
Summary:Column studies were conducted, using iron oxide-coated Aspergillus niger biomass, to examine the removal of arsenic [As(III) and As(V)] from an aqueous solution. The Thomas and Yan models were examined to predict the breakthrough curves. The Yan Model described the data better (based on the R 2 values) when compared with the Thomas Model. The adsorption capacity of the iron oxide-coated biomass estimated by the Thomas Model {1070 μg/g for As(V) and 700 μg/g for As(III)} was comparable to the calculated value of its adsorption capacity {1080 μg/g for As(V) and 880 μg/g for As(III)}.
