The effect of ph and biomass concentration on lead (Pb) adsorption by Aspergillus niger from simulated waste water

Heavy metals released by a number of industrial processes are major pollutants in marine, ground, industrial and even treated wastewaters. Lead is widely used in many industrial applications such as storage battery manufacturing, printing, pigments, fuels, photographic materials and explosive manufa...
