摘要:
建立了一种同时定量测定反应液中苯并噻唑和2-疏基苯并噻唑的高效液相色谱分析方法.该方法采用Hypersil C18( 150 mm x4.6 mm i.d)型色谱柱,以V(甲醇):V(水) =50:50作为流动相(用氨水调节流动相的pH为7.0~8.0);检测波长254 nm;柱温30 ℃ ;流速0.9 mL/min.结果表明,待测物苯并噻唑和2-疏基苯并噻唑在上述色谱条件下分离良好,两种物质的质量浓度线性范围分别为0.047~0.426 g·L-1和0.059 ~0.273 g·L-1,检出限分别在1.23 ×10-3g·L-1和0.78 × 10-3g·L -1,加标回收率分别在98.20 % ~101.03%和98.78 % ~99.76% ,测定结果的最大相对标准偏差分别为0.45%和0.63 % .
Abstract:
A method was presented for the simultaneous determination of benzothiazole and 2-mercaptobenzoth-iazole in the reaction liquid by high performance liquid chromatography (HPLC). The analysis was performedon a Hypersil C18 column ( 150 mm x4.6 mm i.d) with 50 ;50 methanol-water as the mobile phase ( mobilephase with ammonia ,pH =7.0 ~8.0 ) at a flow rate of 0.9 mL/min. The samples were detected at 254 nmwith an UV detector and the column temperature was 30 ℃. It was found that benzothiazole and 2-mercapto-benzothiazole could be well separated under the chromatographic conditions. The linear ranges of the massconcentration were 0.047 ~0.426 g/L and 0.059 q/L~0.273 g/L respectively. The recoveries for them were98.20% ~ 101.0 3% and 98.78 % ~99.76% . The maximum relative standard deviations were 0.45 % and0.63 % for benzothiazole and 2-mercaptobenzothiazole.
