Arsenic and selenium by hydride generation

Any hydride atomic absorption analytical method can be thought of as being composed of three steps. 

Since only inorganic arsenic and selenium can be reduced to the corresponding hydride, organic species of these elements should be converted

Goulden et al. [123] have described a semi-automated system for the determination of arsenic and selenium by hydride generation-industrively coupled plasma atomic-emission spectrometry. Sediments are brought into a solution by fusion with sodium hydroxide.
