| titleOfInvention | Method for measuring content of bromide ions in brine by gas chromatography |
| abstract | The invention discloses a method for measuring the content of bromide ions in brine by gas chromatography. The method comprises the following steps: a. preprocessing a sample, namely, adding an acidifying agent, a derivatizing agent and an oxidizing agent into the brine in sequence, and uniformly mixing for reaction; fully reacting and adding an extracting solvent for extracting; filtering supernatant liquid by anhydrous sodium sulfate for later use; b. measuring the content, namely measuring the content of the bromide ions in the brine processed in the step a by a gas chromatograph, wherein a detector in the gas chromatograph is a hydrogen flame ionization detector. According to the method, the operation is simple, quickness is achieved, the sensitivity is high, the cost is low, the selectivity is good, the impurity interference is slight, the detection result is accurate, and the repeatability, the recovery rate and the precision are good. |
