Abstract

Adsorption of pollutants is regarded as quite efficient methods of aqueous waste treatment. Therefore, the paper reports elemental composition and preliminary investigation of native Gmelina arborea sawdust as phosphate sorbent from aqueous phase. The native Gmelina sawdust was sourced, thoroughly cleaned, and pulverized. Thereafter, the elemental composition (using AAS and SEM) and adsorption (batch wise adsorption process) characteristics of the native sawdust towards PO43- were determined. Assessment of the contact time and mass of the adsorbent effects during the sorption of PO43- are also carried out. The results of elemental composition showed that the Gmelina sawdust was principally; Cu, C, and K. The kinetics studies for the removal of the adsorbate implied that the process attained equilibrium in about 100 min, with % removal of PO43- as 56.80. From the effect of dosage of adsorbent on the sorption studies, it was found that the more suitable ratio of adsorbate to biosorbent is; 1 M: 12.8 g. The biosorption of the phosphate by the sawdust was also confirmed by SEM micrographs. The SEM images after the adsorption process produced rough and irregular surface against the more regular and smooth morphology of the sawdust before the sorption. Having seen that native Gmelina sawdust is viable for removal of phosphate, we wish to recommend that more studies of removal of phosphate from aqueous solution be carried out using a modified form of the sawdust.
