Název v původním jazyce

Biosorption of mercury on magnetically modified yeast cells

Popis výsledku v původním jazyce

Brewer?s yeast (Saccharomyces cerevisiae subsp. uvarum) cells were magnetically modified with water based magnetic fluid and used for biosorption of mercury in batch system. The biosorption process was fast; 80% of biosorption occured within 60 min and equilibrium was achieved at around 90 min. The maximum Hg2+ biosorption capacity was 114.6 mg/g at 35 degrees. The results were well fitted to the Langmuir isotherm. The applicability of two kinetic models including pseudo-first order and pseudo-second order model was estimated on the basis of comparative analysis of the corresponding rate parameters, equilibrium capacity and correlation coefficients. Results suggest that chemisorption processes could be the ratelimiting step in the biosorption process.Biosorption of heavy metal ions from artificial wastewater was also studied.
