不同方法测定化纤钛白中总钛含量的比较

COMPARISON OF VARIOUS METHODS FOR DETERMINATION OF TOTAL Ti CONTENT IN TiO 2 FOR SYNTHETIC FIBRES

进行了不同方法测定化纤钛白中钛含量的比较实验，发现：采用不同的方法（国标ＧＢ１７０６—９３和日本工业标准ＪＩＳＫ１４０９—１９９４）标定硫酸高铁铵溶液的浓度，标定结果偏差不大（＜００６％），说明由于标定方法的不同引起的钛含量测定结果的偏差较小（＜０１％）；不同分析人员引起的操作误差较小，一般偏差＜０１％。

A comparison test has been carried out to check the difference among various methods for determination of Ti content in TiO 2 for synthetic fibres It has been found that the deviations of the concentrations of ferricammonium sulfate calibrated by various methods (GB 1706—93 and JIS K 1409—1994) are small (<0 06%),i e. the deviation of the determination of Ti content will not too big (<0.1%). The deviation,caused by different operators, of the results of Ti content is less than 0.1%
