| dc.description.abstract | Due to the varying degrees of chemicals used in paint industries, the resulting effluent contains appreciable concentrations of toxic metals and inorganic anions which reduce the quality of the receiving streams, aquatic life and adverse effects on human health. This research aimed at determining the effectiveness of composites of Corn cob, Coconut Husk and bread fruit peels in purifying selected paint effluents through the assessment of their physicochemical properties before and after treatment using column adsorption technique. The experimental conditions observed were pH 4 and 8; adsorbent doses of 1g and 2g. Standard laboratory techniques involving the use of Atomic Adsorption Spectrophotometric method were adopted to determine the physicochemical properties of the effluent samples. The physicochemical results showed that the composites were effective in the removal of total solid, turbidity, colour, phosphate, nitrate, chloride, copper and cadmium while the values of COD, BOD, Lead and sulphate recorded noticeable increase on the treated effluent samples. The best experimental conditions according to the adsorption capacity were pH 4 and 1g adsorbent dose. The efficiency removal for heavy metal and inorganic anions in the effluent samples after treatment was in this order: Cl- ˂ Cu˂ NO3– ˂ PO4- ˂ Cd. Considering the values of R2 for the models fits to the experimental data, it can be concluded that all models can be used reasonably well to describe the behaviour of the adsorption of cadmium, copper, chloride, nitrate and phosphate, except for the partly negative values of Bohart – Adams and Thomas models. This research work shows that the use of corn cob, coconut husks and breadfruit peels as composite is more effective in reducing the concentrations of physicochemical properties of paint effluents. | |
