采用甲醇作为萃取剂萃取10分钟,通过涡旋振荡萃取样品中的异噻唑啉酮类物质和酚类抗氧化剂,萃取液离心后采用ZORBAX SBC~(18)(5μm,4.6 mm×250 mm)色谱柱进行分离分析,以乙腈、水为流动相梯度洗脱,二极管阵列检测器检测,检测波长为220 nm,外标法定量,建立了高效液相色谱法(HPLC)测定胶黏剂中异噻唑啉酮类防腐剂及酚类抗氧化剂含量的共检出方法。在系列混合标准工作溶液浓度范围内,目标物的峰面积与其质量浓度之间呈现良好的线性
Extraction was performed with methanol for 10 minutes. The isothiazolinones and phenolic antioxidants were extracted by vortexing. The extracts were centrifuged and chromatographed on a ZORBAX SBC 18 (5 μm, 4.6 mm × 250 mm) The column was separated and analyzed with acetonitrile and water as the mobile phase gradient elution, diode array detector detection, detection wavelength of 220 nm, external standard method to establish a high performance liquid chromatography (HPLC) determination of isothiazole Methods for the determination of the content of ketones and phenolic antioxidants. In the series of mixed standard working solution concentration range, the target peak area and its mass concentration showed a good linear
