Abstract |
Pulse differential polarography was found to be a more sensitive and precise method than linear sweep voltammetry for the determination of NTA as the bismuth complex in natural and waste waters. Indium was a less satisfactory complexant. Relative standard deviations of less than 5% were obtained by the dual cell pulse differential technique at 1 ppm NTA and calibrations were linear from 0.01 to 4 ppm. Copper caused low analytical results for NTA. No other significant interference by metals or complexants was found. An acetate electrolyte was much better than chloride for the determination of bismuth-NTA complex in sewage-type samples. Recommended procedures are given in the appendix. (EPA) |
