采用高效液相色谱法（ Ｈ Ｐ Ｌ Ｃ） 测定了对笨二甲酸（ Ｔ Ｐ Ａ） 接触人群尿中 Ｔ Ｐ Ａ。分析条件：μ Ｂｏｎｄａｐａｋ Ｃ１ ８ 柱４ ．６ ｍ ｍ ×１５０ｍ ｍ ，甲醇－ ５ ｍ Ｍ 氯化四丙胺水溶液（１ ：９ｖ／ｖ）（ｐ Ｈ７ ．０） 为流动相，紫外检测波长为２３８ｎ ｍ ，检测尿中 Ｔ Ｐ Ａ 含量的线性范围为０ ．１ ～２０ ．０ｕｇ／ｍｌ（ｒ ＝ ０ ．９９７） ，平均回收率为９７ ．９４ ％±２ ．６８ 。本法样品处理简单易行，灵敏准确。可用于职业人群尿中 Ｔ Ｐ Ａ 的检测。
High-performance liquid chromatography (HPLC) was used to determine urinary TPA in contact with stupid dicarboxylic acid (T P A). Analysis conditions: μ Bondapak C1 8 column 4. The mobile phase was 6 m × 150 m m and methanol-5 m M aqueous solution of tetrapropylammonium (1: 9 v / v) (p H7 .0) was used as mobile phase. The UV detection wavelength was 238 nm. Range is 0. 1 ~ 20. 0ug / ml (r = 0.997), the average recovery was 97. 94% ± 2. 68. The sample processing is simple, sensitive and accurate. Can be used for occupational population urine T P A detection.
