Abstract
A method is described for the determination of Barium, Manganese and Nickel elements in waste water samples by graphite-furnace atomic absorption spec trometry (GFAAS). There were serious depressing interferences in the direct determination of Ba, Mn and Ni elements in waste water samples by GFAAS. U sing Ascorbic and Citric acids as masking agents. However, these interferen ces could be eliminated. The success of the method is verified by comparing the results obtained by GFAAS using masking agents and those obtained by I CP-atomic emission spectrometry (ICP-AES) using standard addition method wh ich was done by us((6)).
