USING CELLULOSIC MATERIALS TO REMOVE HEAVY METALS FROM WATER
Literature related to bioremediation of toxic metal ions from aqueous solution, using various cellulose-based resources and products, is briefly reviewed. Studies have proven the effectiveness of a very wide range of cellulosic materials, including wood powder, cellulosic fibers, plant materials, and biomass from bacteria and fungi in removing lead, cadmium, chromium, and many other ions. Sorptive capacities often can be enhanced by chemical treatment, derivatization, of by pyrolysis to form activated carbon products. Though the words “ion exchange are often used to describe the mechanism of uptake, it is clear that chemical complexation – offering a degree of metal-selectivity – is often involved. Bioeremediation offers a way for cellulose-based industries to contribute to cleaning up aqueous environments.
