The need for the removal of contaminants from the aqueous environments cannot be overemphasised. This is because of the significant threats they pose to the health and consequently the well-being of both man and other living creatures. In this chapter, we consider the techniques which have been reported for the remediation of water polluted by the often-overlooked oxyanions. While methods such as chemical coagulation, electrocoagulation, reverse osmosis have been utilised for the management of few of these inorganic pollutants, adsorption technique appears to have received more attention in removing all of them. This is possibly because of the simplicity, relatively low-cost and effectiveness of the technique. In particular, ion-exchange technology was reported to offer a very versatile and effective means of removing these oxyanions from water/wastewater. |
