摘 要:采用HPLC建立了一种测定有害酚(苯酚[1]、2,6-二氯苯酚、2,4-二氯苯酚[2]、2,4,6-三氯苯酚[3])的定量分析方法,用Wondasil C18为填充物的不锈钢柱,以甲醇+乙腈+磷酸水溶液为流动相,选择225 nm为检测波长进行检测,结果表明本方法的有害酚的浓度和峰面积之间有良好的线性关系,满足定量分析要求。该方法具有快速、简便、准确、重现性好等特点。

HPLC Method for Phenols in Industrial By-product Salts
FAN Kai, QIN Liu- qiong (GreenTech Laboratory Co.,Ltd., Shanghai 201612, China)
Abstract:A quantitative method for the harmful phenol (phenol, 2,6-dichloropheno, l,2,4-dichlorophenol, 2,4,6-trichlorophenol) was established using HPLC equipped with a UV detector at a wavelength of 225 nm. The test sample was separated through a stainless steel column packed with C18 filler; and a mixture of methanol, acetonitrile and phosphoric acid solution was served as mobile phase. The validation results, linearity, precision and recovery, of four harmful phenols all met the requirement. This method is rapid, simple, accurate and reproducible.
Key words:industrial by-product salt; harmful phenol; HPLC
