摘　　要： 铊的相态分析既是研究自然环境中铊的迁移和生态效应的指标 ,也是指示寻找大型隐伏矿床如铊、金、汞、砷、锑等矿的手段。为了进一步探讨颗粒物中铊相态提取的技术和方法 ,在优化干扰物分离条件下 ,采用七步法提取了几种不同粒径硫酸废渣中铊的相态 ,比较了废渣研磨前、后各相态铊的异同。 Phase analysis of thallium is not only the research objective of thallium migration and ecosystem effect of thallium in nature environment, but also the guide to find hidden large scale deposit such as TI, Au, Hg, As and Sb ore. The phases of sulfuric acid slag of various sizes were drawn by seven-step method in the improved separation condition of disturber, and phases of thallium were compared before and after the slag was grinned to analyze phase migration.
