甲基紫法测定鉈,是基于甲基紫和卤化鉈生成的固态化合物用苯、甲苯、醋酸戊酯等溶剂提取而进行比色的。不久以前(?)等拟訂了用銅絲接鍍去干扰元素而进行测定的快速法。根据我們的实驗,此法較难掌握,接鍍一般都需达7～8次;接鍍次数过多,影响酸度,以致不能立刻进行显色。我們制訂了用盐酸蒸干除去干扰影响的快速法測定鉈,比較可以获得令人满意的結果。矿石用酸分解后,在溶液中能和甲基紫生成固态化合
Methyl violet method for the determination of thallium is based on methyl violet and thallium halide generated solid compounds extracted with benzene, toluene, amyl acetate solvent extraction and colorimetric. Not long ago (?) And other drawn up with copper wire plated to interfere with the rapid determination of the elements. According to our experiments, this method is more difficult to grasp, generally need to reach 7 to 8 times plating; plating too many times, affecting the acidity, so that can not immediately color. We have developed a rapid method of removing interference with hydrochloric acid evaporated to determine the thallium, compared to get satisfactory results. Oxygen decomposition of the ore, the solution can be generated with methyl violet solid-state compound
