毛细管气相色谱法测定三苯基膦的含量 前言：采用１０ｍ×０．２５ｍｍｉｄＯＶ－１０１石英毛细管柱，氢火焰检测器（ＦＩＤ），蒽酮作内标物，建立了毛细管气相色谱法分析三苯基膦的方法。该法快速、准确，其回收率为９９．２％—１００．３％。 In this paper,a method was established for the determination of the content of triphenyl phosphine by a 10m×0 25mm i.d.OV 101 fused silica capillary column and FID detector The column temperature was programmed from 130℃ to 250℃ at 20℃/min The internal standard was anthrone It was rapid and accurate,and could be easily used for industrial process The recovery of triphenyl phosphine ranged from 99 2% 100 3%
