Mechanism of Adsorbing Cadmium in Electroplating Wastewater by Water-Washing Waste Saccharomyces cerevisiae

Abstract:

The function mechanism of water-washing waste saccharomyces cerevisiae and cadmium in electroplating wastewater was studied by desorption by washing experiment，chemiscal modification experiment and XPS analysis of water-washing saccharomyces cerevisiae pre-adsorbing and post-adsorbing cadmium. The desorption by washing experiment result show that chemiscal adsorption is the main adsorption form; phsicalffunt chemiscal modification experiment result show –NH2 –COOH was important groups of water-washing saccharomyces cerevisiae effecting on cadmium, XPS analysis result show that effect on water-washing saccharomyces cerevisiae and cadmiun was not only on the surface but also in the cells.
