Speciation of Aluminum in Natural Water by A.C.Oscillopolarography Using Chlorosulfophenol-S
Abstract:
A simple and reliable electroanalytical method for the fast determination of different aluminum species(total AlT, acid soluble Alr, monomeric Ala, inorganic monomeric Ali and organic monomeric Alo) in natural waters by a.c.oscillopolarography using chlorosulfophenol-S(SCPS) is described.The method was successfully applied to analyze different species of Al in 20 real samples.A program using C language designed by authors was applied to prove the theoretical foundation of the proposed method.The program was also applied to compare three kinds of reagents with different structures to ascertain the optimum pH range for speciation of Al in real water.It is concluded that the complexing ability of a certain reagent with Al mainly depends on the complexing constant and acid dissociation constant Ka, as well as the chemical structure of the ligands.
