分光光度法测定合成聚酯催化剂中的钛

Spectrophotometric Determination of Titanium in Catalyst for Synthetic Polyester

将在聚酯合成中使用的一种白色粉末状催化剂溶解在硫酸-硫酸铵溶液中，用分光光度法测定其中的钛，选择420hm为测试波长，钛含量在0～35μg／ml范围内服从比尔定律，结果的相对标准偏差小于2％，回收率为102％。

Sulfuric acid and ammonia sulfate solved sample. Spectrophotometric determination of titanium in white powder catalyst. The optimal absorption was at 420nm. Beer＇s law is obeyed in the concentration rangs of 0～35μg/mL of titanium. The standard deviation of method is less of 2 % , the recovery is 102 %.
