A simple and convenient method is described for the determination of low concentration beryllium in industrial wastes. It is based on the differential pulse polarographic reduction of Be2+ in complexing medium of dimethyl formamide in acetate buffer. Linearity of the calibration curve was observed in between 0.05 to 10 ppm. The limit of determination was achieved 0.01µg/ml. The measurements were found quantitative in terms of standard deviation ±0.07 and the comparison of results by UV-Vis spectrophotometric method suggests validity of the DPP method.
