氨羧络合剂是在1945年才开始应用在分析化学中,二十世纪五十年代曾有了极迅速的发展,有关发表的论文,数以千计,成为现代分析化学中重要的新方法。五六年六月我国才开始了氨剂的试验研究工作。截至目前为止,我厂已有十多种元素,二十多种试验利用了络合剂。 原理与特点:氨羧络合剂能与许多种金属元素形成稳定的能溶性络合物,因此许多元素都能直接或间接的用络合剂来测定,这样就简化了很多复杂物质,如矿石,金属合金的分析问题,大大的提高了工作效率。 用途和意义:氨羧络合剂滴定法我厂是国内首先大量采用的一个,现已能应用于钢铁,铅合金,铜合金,药品及槽液的分析,大大提高工作效率,降低成本。如铅合金定镁,球墨铸铁定镁,钢铁定镍,氯化钡,磷酸盐的测定等皆提高工作效率3～10倍,保证分析的准确度。
Ammoniacarbamide was started to be used in analytical chemistry only in 1945 and developed very rapidly in the 1950s. The published papers, in thousands, became an important new method in modern analytical chemistry . In June of this year, China started the experimental research on ammonia agent. So far, I plant has more than 10 kinds of elements, more than 20 kinds of tests using the complexing agent. Principle and characteristics: Ammonia carboxy complexing agent can form stable soluble complex with many kinds of metal elements, so many elements can be directly or indirectly measured with complexing agent, thus simplifying a lot of complex substances such as ore , Metal alloy analysis problems, greatly improving the work efficiency. Uses and Significance: Ammonia carboxylic complexing agent titration method Our factory is one of the first widely used in China, and now it can be applied to the analysis of steel, lead alloy, copper alloy, medicine and bath solution, greatly improving work efficiency and reducing cost. Such as the determination of lead alloy magnesium, ductile iron magnesium, nickel steel, barium chloride, phosphate determination of all improve work efficiency 3 to 10 times, to ensure the accuracy of the analysis.
