Anodic detection of arsenic III in a flowthrough platinum electrode

Apr 1 1980 Arsenic III can be amperometrically detected by oxidation at a platinum or gold electrode in perchloric acid solutions Platinum is the preferred material because halides interfere with the oxidation of arsenic III at gold electrodes The limiting current for arsenic III at the platinum electrode is less than the Apr 1 1980 Arsenic III can be amperometrically detected by oxidation at a platinum or gold electrode in perchloric acid solutions Platinum is the preferred material because halides interfere with the oxidation of arsenic III at gold electrodes The limiting current for arsenic III at the platinum electrode is less than the

Solubility of platinumarsenide melt and sperrylite in synthetic basalt

In the first platinum solubility in the synthetic basalt was determined without added arsenic by equilibrating the sample with a platinum source embedded wire or bead in a gasmixing furnace In the second the sample plus a Ptarsenide source was equilibrated in a vacuumsealed fused quartz tube containing a In the first platinum solubility in the synthetic basalt was determined without added arsenic by equilibrating the sample with a platinum source embedded wire or bead in a gasmixing furnace In the second the sample plus a Ptarsenide source was equilibrated in a vacuumsealed fused quartz tube containing a
