|Abstract: ||Dyes are usually present in trace quantities in the treated effluents of many industries. The effectiveness of adsorption for dye removal from waste waters has made it an ideal alternative to other expensive treatment methods. This study investigates sorption properties of Tectona grandis, Ceiba pentandra and Terminalia superba sawdust for the adsorption of Vat Yellow-4, Vat Red-1 and Natural dyes in water bodies. Physical parameters of the wood sawdust and textile dye such as pH and moisture content were determined. The dye removal capacities of the various wood species were also calculated. The pH of the dyes and wood sawdust ranged from 5.93 to 9.47; and 5.06 to 8.59 respectively. The moisture content (%) also ranged from 3.00 to 4.00 with an average of 3.50. The dye removal percentage (%) by Tectona grandis, Ceiba pentandra and Terminalia superba wood sawdust were respectively found to range from 18.39 to 44.46, 9.24 to 46.65 12.66 to 63.56 for the adsorption of the various dye samples used. Adsorption of the textile dyes unto the selected Ghanaian wood sawdust conformed to the Type I isotherm according to the classification by IUPAC. The Freundlich model showed a better fit for the experimental data and could be attributed to the heterogeneous surface energies and exponential distribution of active sites which are characteristic of such cellulosic materials.|
