Waste Fungal Biomass for Mercury Biosorption – Column Studies

Abstract:

Article Preview

Granulated Tolypocladium biomass (industrial waste) was tested as mercury biosorbent in continuous mode (fixed bed column). Supplied material contained approx. 70% of fungal biomass and 30% of inert material (diatomaceous earth). Prior to column experiments, batch sorption was also performed. The results of batch experiments were compared to our previous results obtained for powdered biomass (100% biomass material) and an important drop of sorption capacity was observed. For column experiments, the bed height and flow rate were kept constant and the influence of both initial mercury concentration and bead size was investigated. The Adams Bohart, the Thomas and the Yoon and Nelson models were used for the characterization of breakthrough curves.
