Abstract
The application of inductively coupled plasma mass spectrometry (ICP-MS) to the simultaneous determination of chlorine, bromine and iodine in the National Bureau of Standards (NBS) Standard Reference Material (SRM) 1648 Urban Particulate is described. The potential of ICP-MS for simultaneous multi-element trace determinations after a conventional dissolution procedure is illustrated. Various possible methods for including the halides are considered, and various sample dissolution procedures are investigated. Data presented for the NBS SRM 1648 Urban Particulate are considered in terms of the previously published results and polyatomic ion interferences from sample fusion procedures. It has been shown that the method has great potential for the determination of total chlorine, bromine and iodine in environmental dust and other samples.
