摘要：

The anion exchange behaviour of hydrous titanium oxide (HTO) has been exploited for the management of industrial waste effluents contaminated with chromium(VI). The adsorption of chromium(VI) by HTO (74.0-140.0 micron) in the pH range 0.5-8.0 has been studied. It is found that the adsorption of chromium(VI) by HTO is at a maximum in the pH range 1.5-2.0. The interference of diverse foreign ions such as nitrate, chloride, sulfate, phosphate, calcium, magnesium, nickel, iron(III), barium etc. on the adsorption of chromium(VI) by HTO at optimum pH has been investigated by a batch-operation technique. Break-through capacity, adsorption and elution of chromium(VI) using HTO have been studied. It is found that HTO could be reused as an adsorbent for chromium(VI). Finally, chromium(VI) was recovered as insoluble chromate compound from waste effluent of Hindustan Motor Limited (HML) of Hooghly, West Bengal, India.
