硅钼黄和硅钼蓝测定三元复合驱采出水中硅的比较

Determination of Silicon Content in ASP Flooding Produced Water by Silicon - Molybdenum Yellow and Silicon - Molybdenum Blue

三元复合驱采出水中硅含量的测定分别采用硅钼黄分光光度法和硅钼蓝分光光度法,并对两种测试方法进行了比较。实验结果表明,当样品的硅离子浓度较低时,采用硅钼蓝法的精密度要高于硅钼黄法。当硅离子浓度较高时,硅钼黄法精密度高于硅钼蓝法。因此,建议在测试三元复合驱采出水硅含量时,可根据样品的硅含量选取适当的分析方法。

Silicon content in ASP flooding than that ＇of the silicon -molybdenum yellow and silicon -molybdenum blue were applied for the determination of silicon produced water. The results showed that the precision of silicon - molybdenum blue was higher molybdenum yellow when the silicon content of water was low. It was opposite when the silicon content of water was higher. Therefore, it was suggested that according silicon content of the sample, the appropriate test method can be selected.
