Biosorption of Phenols and Dyes on Albizia lebbeck (Rattle Seed) Pod: Equilibrium and Kinetic Studies (original) (raw)
Introduction One of the major problems of the industrial waste is the great amount of wastewater produced and the high investment needed for the treatment of this effluent before it is released in the environment. Pollution of water is a major environmental problem. The self-purification capacity of surface water and changes in the availability of food; have been extremely threatened by industrial effluents which are major sources of pollutants in the aquatic ecosystems (Udiba et al., 2014). Modern industry is to a large extent responsible for the contamination of the environment. Lakes, rivers and oceans are being overwhelmed with bacteria and waste matter. Among toxic substances reaching hazardous levels are heavy metals and organic pollutants (Vieira and Volesky, 2000).
