This paper is concerned about a renovated method for bio- absorbing Pb~(2+) by using living cells of Sphaerotilus natans FQ32 as an agent in aqueous solution simulated wastewater.For the research purpose,we have done a series of experiments to determine and de- fine the influential factors on the biosorption process,such as the ini- tial concentration of Pb~(2+),the biomass concentration,the bacteria culturing time,pH value,temperature and the adsorbing time to Pb~(2+).The results have shown that,at the low...
