摘要：通过采用分光光度法对聚酯用钛系催化剂中钛元素含量进行测定,从精密度,回收率,重复性和检出限四个方面对其进行方法学评价,建立了对该类催化剂中钛元素分析方法。结果表明,该方法回收率在100%-105%之间;精密度测试RSD为0.33%,检出限和定量限分别为0.0455mg/L和0.0152mg/L。
Determination of titanimum dioxide in titanium-containing catalyst for polyester by spectrophotometric was studied.The method was evaluated from precision,recovery,repeatability and detection limit.The recovery was between 100%-105% and the relative standard deviation was 0.33 %.The limits of detection and quantitation were 0.0455mg/L and 0.0152mg/L respectively.
