Detection of Essential Trace Element of Chromium by Electroanalytical Methods

A detailed study of essential ultra trace element of chromium present many of industrial waste lakes of western rajasthan. Aconvinent method of electroanlytical technique used for the essential trace element present in the industrial waste water as a polarography method for identification of essential trace element by using concentration of ppm to ppb. According to this method prepare solution of sodium chromate as a stock and identify electroanalytical potential by using as a supporting electrolyte 0.05 M HCl + 0.25 M NaCl give a sharp peak at ࡱ૚ ૛ ൗ = 0.91(V) and result compare with other electroanalytical instrument like UV-Vis Sprctrophotometer, Atomic absorption spectroscopy
