Abstract
A method to determine the trace level of arsenic in scalp hair by the hydride generation(HG)-inductively coupled plasma(ICP) spectrometry is described. The optimum conditions for the generation of arsine(<TEX>$AsH_3$</TEX>), and the interference effects from the concomitant ions were studied. Severe interference effect from Ni(II) is circumvented by the coprecipitation of arsenic with <TEX>$La(OH)_3$</TEX>. The detection limit of arsenic is 0.3ppm and the arsenic contents in scalp hair ranged 10~20ppb.
