摘要
The research of the effects of surfactants on coloring reaction between titanium and phenyl fluorone was developed.A survey of coexisting elements in the houttuynia cordata thunb was carried out by X-ray fluorescence spectrometry,and a series of interference tests and analyses were performed.The interference can be eliminated by processing through high temperature cineration and adding ascorbic acid.A new method of determination of titanium in houttuynia cordata thunb was established by phenyl fluorone spectrophotometry in the presence of Emulsifier OP.The results showed that Beer’s law is obeyed within the range of 0~0.32 μg·mL-1 for titanium.The relative standard deviation(RSD) was 1.9%~2.0%,and the recovery was 96.8%~100.6%.The method was applied for determination of titanium in houttuynia cordata thunb with satisfactory results.
The research of the effects of surfactants on coloring reaction between titanium and phenyl fluorone was developed. A survey of coexisting elements in the houttuynia eordata thunb was carried out by X-ray fluorescence spectrometry, and a series of interference tests and analyses were performed. The interference can be eliminated by processing through high temperature cineration and adding ascorbie acid. A new method of determination of titanium in houttuynia eordata thunb was established by phenyl fluorone speetrophotometry in the presence of Emulsifier OP. The results showed that Beer's law is obeyed within the range of 0 -0. 32 ug . mL^-1 for titanium. The relative standard deviation(RSD) was 1.9% - 2.0% , and the recovery was 96. 8% - 100. 6%. The method was applied for determination of titanium in houttuynia cordata thunb with satisfactory results.
