0 for Ni (II) by using lg of modified silica sand for the contact time periods ranging from 10-120 min at 25°C. , the period after which no adsorption takes place), all the further experiments are limited up to that time. 5, temp = 25°C, dose = lgm/50ml adsorbent, rpm = 150). 10). 5 at 25°C. It can also be observed that for the present system, the equilibrium is independent of the adsorbate concentration. The curves obtained are single and smooth indicating the formation of monolayer on the surface of adsorbent during the removal process.

Heavy metals have a great affinity to attack sulphur bonds, protein, carboxylic acid, and the amino group, thereby disrupting the cell's metabolism. An excessive presence of these metals in living species results in carcinogenic, mutagenic, teratogenic, and other toxic effects on them. Once they are accumulated in living tissues, they disturb microbial processes and have been reported to be fatal [49, 50]. A slight excess of metals in water is extremely toxic to fish and can also damage algal growth.

A. A stock solution of Ni (II) was prepared by dissolving nickel sulphate in 1000 ml of distilled water. Then this solution was used to prepare a working solution of nickel Ni (II) of different concentrations. 42 ECONOMIC REMOVAL OF METALS FROM AQUEOUS SOLUTIONS b. A stock solution of chromium was prepared by dissolving potassium dichromate in 1000 ml distilled water, and used for preparation of chromium solution at various concentrations range. 0 x 10-2 M NaC104. Batch experiments were conducted separately for both the selected metallic species, namely Cr(VI) and Ni(II), using both nano alumina and nano iron.
