- Abstract
Heavy-metals water pollution is without doubt a significant environmental problem in the global context. These non-degradable chemical pollutants may be the cause of serious ecological and health issues, due to their ability of penetration and accumulation throughout the food chain exposing humans to slow but certain poisoning. In order to alleviate water stress, several technological solutions for the removal of toxic heavy metals from industrial wastewater have been implemented. The removal efficiency was often limited by the cost-effectiveness, the sludge production and the metal selectivity of the most common physico-chemical processes. Alternatively, adsorption using natural wastes from agricultural and industrial activities is a promising technic that has received great deal of attention recently. It was considered as an economic, efficient, sustainable and green process. Among the used materials, sawdust gained particular interest over other commonly used and was hence extensively reported as a low-cost potent remedial tool. On this basis, the scope of this chapter is to extend the base of knowledge on this natural adsorbent, its properties and its application fields. This chapter focuses mainly on the potential utilization of sawdust in the treatment of heavy metals-contaminated wastewater. This would contribute to the development of an entirely commercially viable process of depollution. This chapter compiles the literature on the potential utilization of sawdust as an adsorbent in order to explore its efficiency in removal of toxic metals, offers a discussion of the used surface characterization and pretreatment techniques to improve the sawdust adsorption ability and suggests future research directions for the development of efficient wastewater adsorption processes using this material.
