摘　　要：介绍了三氯化钛（ＴｉＣｌ３）与氧反应，以钨酸钠（Ｎａ２ＷＯ４）作指示剂，用重铬酸钾溶液滴定过剩三氯化钛来测定水中溶解氧的方法。本法与碘量法比较，结果表明方法准确、快速。Some problems of quality control in detection of organic pollutants with gas chromatography are stated. The detecting precision and recovery of standard should be based on the property of samples and detected species. It is suggested that detecting methods of organic pollutants,quality control method and index for the reality in China should be established as soon as possible.
