摘要
建立高效液相色谱法(HPLC)测定邻苯氨甲基苯酚(PMP)氧化降解过程中的质量浓度变化。采用Hypersil ODS-C18反向色谱柱(4.6 mm ×250 mm ,5μm),流动相为甲醇-水(80∶20),检测波长243 nm ,流速1 mL/min ,外标法定量测定其质量浓度。液相测定结果表明,PM P质量浓度在5~100 mg/L范围内,被测溶液质量浓度与峰面积呈良好线性关系,平均加标回收率为93.22%~107.62%;试验精密度RSD=0.20%(n=8),重现性良好。该液相方法可用于邻苯氨甲基苯酚氧化反应的测定。
A method for determination the oxidative degradation of 2-((phenylamino ) methyl)-phenol was established by HPLC with Hypersil ODS-C18 chromatographic column (4 .6 mm × 250 mm ,5 μm) ,methanol/water (80∶20 ,V/V ) as mobile phase ,UV-243 nm as detector and flow rate as 1 mL/min .Experimental results showed that linear relationship and repeatability are good in the range from 5 to 100 mg/L .The recovery is at the range of 93 .22% -107 .62%and RSD is 0 .20% (n=8) .It can be applied to analysis of the reactant concentration in the oxidative reaction .
