离子色谱法测定油田有色地层水中的碳酸根和碳酸氢根

Determination of Carbonate and Bicarbonate in Colored Oilfield Underground Water by Ion Chromatography

  • 摘要: 针对油田有色地层水中碳酸根和碳酸氢根含量的测定,建立了一种间接光度非抑制离子色谱法.优化了固定相和流动相条件,发现碳酸盐碳的总量和碳酸氢根峰高在0.24~12 mmol/L范围内具有良好的线性关系.对油田有色地层水进行了测定,结果令人满意.

     

    Abstract: A new ion chromatography has been set up to determine the carbonate and biocarbonate in colored oilfield water samples. By optimizing the chromatographic conditions, the total carbonate-carbon can be analyzed in less than 8 min, and then the content of the carbonate and bicarbonate in the sample is conveniently calculated through acid-base equilibrium. The linear relationship between the total contents of carbonate-carbon and responses is satisfied in the range of 0.24~12 mmol/L. The limit of detection of this method is 0.24 mmol/L total carbonate-carbon, relative standard deviation is less than 5.0% and recovery is 95%~105%.
