摘要
提出了高效液相色谱法测定苯并三氮唑产品以及工业循环冷却水中苯并三氮唑含量的方法。色谱分离采用Kromasil C18(4.6 mm×250 mm,5μm)色谱柱,以乙腈-水(25+75)为流动相,流量为1.0 mL·min^-1,检测波长为260 nm。苯并三氮唑的质量浓度在3.84-76.8 mg.L-1范围内与峰面积呈线性关系,平均回收率为96.4%。
A HPLC method for determination of benzotriazole(BTA) and its application to the analysis of circulating cooling water sample was proposed.The Kromasil C18 chromatographic column(4.6 mm×250 mm,5 μm) was used for the separation,and a mixture of acetonitrile and water(25+75) was used as mobile phase with flow-rate of 1.0 mL·min^-1.UV-detection at 260 nm was adopted.Linear relationship between values of peak area and mass concentration of benzotriazole was obtained in the range of 3.84 to 76.8 mg·L^-1.Test for recovery was made by adding standard BTA to a known BTA sample and analyzing by the proposed method,result of average recovery(n=5) found was 96.4%.
