Abstract:The feasibility of simultaneous determination of trace iodine,bromine,selenium and arsenic in geological samples by inductively coupled plasma mass spectrometry was investigated. The signal response of different anion species in different solution mediums was assessed. It is shown that in nitric acid solution the ion signal intensity of I - is much higher than that of IO - 3 and IO - 4. In addition,the observed I - signal in nitric acid solution is not stable. The results from the experiments also show that weak acid solution or ammonia solution is a suitable medium for determination of these elements and addition of ammonia solution is a effective way in eliminating the memory effect from iodine and bromine.
Keywords:inductively coupled plasma mass spectrometry  geological sample  iodine  bromine  selenium  arsenic  memory effect
