| Abstract: | A novel and simple method for electrochemical determination of five fractions of aluminum in natural waters by a.c oscillopolarography in the presence of bromopyrogallol red is presented in this paper.It is mainly based on the direct determination of inorganic monomeric Ali and total monomeric Ala under the conditions of acidic and alkaline buffer solutions respectively.The method has been employed to determine five Al fractions in 30 natural water samples.The results are in agreement with those obtained by Driscoll′s scheme. |
