一、前言顺丁橡胶聚合过程中对于溶剂苯、甲苯中的水分含量,要求严格控制在30ppm以下。对含水在几十个ppm的样品,以往均以经典的弗歇尔滴定法进行。在早期的微量水气相色谱分析的许多尝试中,由于担体、固定液及气路管壁对水的吸附作用和水的较长的保留时 First, the foreword Polybutadiene rubber polymerization process for the solvent benzene, toluene in the water content, require strict control at 30ppm or less. For samples containing a few dozen ppm of water, all previous classical Fowler’s titration. In many attempts of early trace water gas chromatography, due to the adsorption of water by the support, fixative and gas pipe walls and the longer retention of water
