Determination of trace amounts of arsenic using a capacitively coupled microwave plasma combined with hydride generation: applications to sewage sludge, iron and steels

A capacitively coupled microwave plasma (CMP) combined with an arsine generation system for the determination of trace amounts of arsenic is described. Factors affecting the spectral intensity of As 228.8 nm in the CMP were examined, and optimal working conditions for the determination of arsenic we...

Description
Summary:A capacitively coupled microwave plasma (CMP) combined with an arsine generation system for the determination of trace amounts of arsenic is described. Factors affecting the spectral intensity of As 228.8 nm in the CMP were examined, and optimal working conditions for the determination of arsenic were established. A sensitive, precise and practical method for the determination of arsenic in sewage sludge, iron and steels was elaborated.
