Conference paper


The chapter presents a study of the adsorption capacity of zinc ions from aqueous solutions in natural adsorbents (bagasse ash of red variety sugarcane, coconut shell, activated carbon, and bentonite) from Mozambique. As a heavy metal, zinc has maximum allowable concentration in the drinking water of 5 mg/L according to the Mozambican norm. The environmental pollution caused by the discharge of effluents with contents outside the dumping regulations of Mozambique can be reduced by the use of local materials. According to the results of kinetic studies, the models which better adjust were the pseudo-second order which indicate a physical-type adsorption. Bagasse ash of red variety sugarcane presented the higher adsorption capacity while coal had the lower capacity.
