摘要
介绍了用反相液相色谱法定量分析三苯基磷。使用 ODS( 2 50× 4 .6 mm,1 0μ)不锈钢柱 ,以甲醇水 ( 4∶1 )为流动相 ,流速为 1 .5m L/ min,紫外检测器 ,波长 2 54nm,在浓度 0 .4～ 0 .6 mg/ m L的范围内具有较好的线性关系 ,相关系数 r=0 .999。
A reversed phase high performance liquid chromatography method was developed for the separation of triphenylphosphine. The column ODS (250×4.6mm,10μ) was eluted with 4∶1 of methanol and water solution at 1.5mL/min as mobile phase. The fractions were monitored by UVdetector at 254nm.Good linearties were obtained in the rang 0.4～0.6mg/mL (r=0.9999). The results were satisfactory for the quantitative determination of triphenylphosphine in technical products.
