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 c ontinuous Row hydride generation in the system with phase separation was in vestigated using inductively coupled plasma atomic emission spectrometry. T he effect of HCl and HNO3 (for concentrations from 0.01 to 5.0 moll(-1)) an d arsenic on transport efficiency of the metals into plasma was examined. I t 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. Pos sibility of spectral interferences between Cd, Cu and Fe lines on the one s ide and As and Bi lines on the other side was analysed and discussed. (C) 2 001 Elsevier Science B.V.
