Manganese waste water treatment by fungi derived from manganese slag

0

The aim of this study was to isolate a mould from the surface of manganese slag which had strong resistance and high adsorption of Mn2 + , and to determine the effects of initial Mn2 +  concentration, incubation temperature, rotation speed and inoculation amount on adsorption of Mn2 +  from manganese waste water solution. The result showed that a mould (A5) which was isolated from manganese slag had the adsorption rate of Mn2 +  to 97.5% at the initial pH value 6, inoculation amount 2%, rotation speed 150 r/min, a concentration of Mn2 +  500 mg/L, and a temperature of 28°C cultivated for 50 h. As there is no research on adsorption of Mn2 +  from manganese waste water by fungi before, this research showed a theoretical guidance on this field.
