钛酸钡中超微量锰的测定方法探讨

Inquriry upon the Detection Methods of Ultramicromangnese in Barium Titanate

本文在传统分光光度法测定钛酸盐中超微量锰的基础上,采用721型分光光度计,525nm波长,改进了工作曲线底液及空白液的组成,使测定含量低至0.02%,检出最低含达0.0015%,是定量测定钛酸盐中超微量锰的可靠方法.

This paper advances the spectro-photometric methods of de term inating ultramicromanganese in titar-ate, by means of 721-type spectrophotometer. The wave length used 525nm. Is improves the components of the curve's background solution and blank solution in the classic spec Uophotometry. The detection content of this method is 0.02%, and the lowest content is 0.0015%,a reliable quantitative detection method of uitramicromanganese in titanate.
