On the transport of some metals into inductively coupled plasma during hydride generation process

Transport process of Ca, Cd, Co, Cr, Cu, Fe, Mn, Mg, Ni, Zn and Ti during continuous flow hydride generation in the system with phase separation was investigated using inductively coupled plasma atomic emission spectrometry. The effect of HCl and HNO3 (for concentrations from 0.01 to 5.0moll-1) and arsenic on transport efficiency of the metals into plasma was examined. It was observed that not only Cd but also Cu transport in a form of volatile species was significant. The present study also indicated the formation of Co, Cr, Fe and Ni volatile species during hydride generation reaction. Possibility of spectral interferences between Cd, Cu and Fe lines on the one side and As and Bi lines on the other side was analysed and discussed.
