摘要
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。
Terephthalic Acid(TPA) in urine of occupational workers was determined by high performance liquid chromatography.analytical conditions were as follows:μ bondapak C 10 column 4 6×150mm,methanol-H 2O containing 5mM tetrapropylammonium chloride(1∶9v/v)(pH7 0)mobile phase and UV detection at 238nm.The linear range of urinary TPA in the method is 0 1-20 0ug/ml(r=0 997).The average recovery is 97 94%±2 68.The treatment of the sample is simple and practicial.The method is sensitive and precise.It can be used for monitoring the concentration of TPA in urine of occupational workers.
