防腐木材抽提液中杀菌剂(BAC)的测定

Determination of Benzyl-dimethyl-dodecyl-Ammonium Chloride in an Extracted Solution of Preservative-treated Wood

建立了防腐木材抽提液中十二烷基二甲基苄基氯化铵（BAC）的高效液相色谱分析方法。通过使用Venusil SCX柱．将氧化铵溶于V（甲醇）：V（水）=5：1混合液作为流动相，检测波长262nm，在质量浓度10～1000mg／L的相关系数为0．9997．相对标准偏差0．235％，平均加标回收率为100．9％，检出限1．0mg／L。该方法适用于分析防腐木材抽提液中BAC的含量。

The authors developed a high performance liquid chromatography （HPLC）method to analyze Benzyl-dimethyl-dodecyl-ammonium chloride （BAC） from an extracted solution of preservative-treated wood. The parameters of this method were as follows： a venusil SCX separating column; a 5 ： 1 methanol to water volume ratio, ammonium chloride and acetic acid was used as a mobile phase; and a 262 nm wavelength UV detector. The linear correlation of this method was 0. 999 7 at a 10 to 1000 mg/L BAC concentration. The average recovery of spiked samples was 100.9%. The relative standard deviation was 0. 235% and the detection limit was 1.0 mg/L.
