摘要
对示踪剂荧光素性质进行考察，通过对待测水样用KOH调节pH至8，利用荧光法测定油田采出水中示踪剂的含量。该方法简便、快速且灵敏度高，测定值的相对标准偏差在0．167％以内，加标回收率为96．73％～104．00％。
The luminescent properties and stability of fluorescein which is used as a tracer in oilfield produced water have been investigated. The pH of the water samples to be tested should be adjusted to 8 with KOH. The tracer content in oilfield produced water is determined by fluorometry. This method is simple, convenient, and fast, having high sensibility. The relative standard deviation of this method is within 0.167%, and the indexed recovery rates are 96.73%-104.00%.
