Abstract
Hydride generation from solution containing As(III), Bi(III), and Sb(III) by means of different borane reductants and acids using inductively coupled plasma optical emission spectrometry as a detection system was investigated. The As, Bi, Sb, B, C, H, and N lines as well as the OH and CN molecules were recorded. Their intensities in relation to hydride formation conditions were measured. Effects of the HCl, CH3COOH, and C6H8O7 acids as well as the NaBH4, H3B-NH(CH3)2, and H3B-NH2C(CH3)3 reductants on efficiency of the As, Sb, and Bi hydride generation were investigated and discussed. Influence of hydride generation conditions on plasma was studied.
