How to Treat Wastewater in Non-Ferrous Metal Industry?

Ion,-exchange is already being used in the electroplating industry and at least one plant is now in operation treating the effluent from a copper semi-fabricating works. Reverse osmosis as applied to effluent treatment is less well developed, but on first consideration it appears to have the attraction over ,ion,-exchange in being basically simpler and continuous, with no regeneration cycle.

In environmental chemistry, the ,chemical oxygen demand, (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution.It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre (mg/L).A COD test can be used to easily quantify the amount of organics in water.

Conclusion: Both HT and Na-Y adsorbed the toxic ,bichromate, ions more favorably than other sorbents. The high pore volume and the apparent surface area of a non-functionalized MCM-41 were not effective in the adsorption of Cr compounds. Overall, HT was the best choice owing to its appropriate surface chemistry with respect to the Cr oxygenates.
