摘要
阳离子型钻井液处理剂中阳离子的含量(或称作阳离子度)为该物质的总量中阳离子基团所占的质量分数。提出了用改进的四苯硼钾重量法测定阳离子度。试验验证对此类样品的分析,不适合用常规的酸碱滴定法,对所提出的重量法的可行性经岩心回收率试验得到验证。
Percentage content of cation, or named the cation degree, which is the mass percentage of the cation group in the cationic drilling treating agent, was determined by the modified patassium tetraphenyl boronate gravimetric method. It was experimentally proved that the titrimetric method was not suitable to be used in this case. Feasibility of the modified gravimetry was ascertained by the core recovery.
