【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%。更多还原

【Abstract】 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%.更多还原
