| Abstract |
Several analytical methods for possible use in measuring trace amounts of water soluble sulfate anions were reviewed and evaluated. Enzymatic sulfate determination does not appear to be a viable approach until the required enzymes can be obtained commercially. Gas chromatographic analysis of bis(trimethylsilyl)sulfate was studied and, with further development, may be a selective method for the determination of sulfate as well as other oxy-anions. A direct kinetic method, based on the ability of sulfate to catalyze the depolymerization of zirconyl species, was investigated. The method can detect 0.2-20 ppm sulfate and, with a minimum of sample preparation, is relatively selective. |
