电感耦合等离子体质谱法同时测定地质样品中痕量碘溴硒砷的研究Ⅰ．不同介质及不同阴离子形态对测定信号的影响

Determination of Trace Iodine, Bromine, Selenium and Arsenic in Geological Samples by Inductively Coupled Plasma Mass Spectrometry

摘要: 研究了半熔-电感耦合等离子体质谱法（ICP-MS）同时测定地质样品中痕量碘、溴、硒和砷等非金属元素的可行性。重点研究了不同介质中碘以及溴、砷、硒不同形态对测定信号的影响。比较并讨论了在纯水溶液、0.07mol/LNH

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
