EVALUATION OF SPECIFIC-ION ELECTRODE FOR DETERMINATION OF HEAVY METAL

1. CADMIUM, LEAD, SILVER AND CUPRIC ION ELECTRODES

Abstract

Orion solid-state electrodes for heavy metal ions such as for cadmium, lead, silver, and cupric ions were evaluated regarding their limits of detection, effects of pH, in- terferences by other ions, and applications to urine analyses.
The authors are convinced that these electrodes precisely detect low levels of each corresponding ions without notable interference by pH or other ions, and that urine analyses may be possible by the use of adequate masking agents for interfering ions through the Known Addition Method.
