- 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.
