Determination of Boron in Frac Flowback Fluid by Titration
The fracturing process generates a significant volume of complex flowback fluids,which pose considerable challenges for treatment.Boron,a trace element present in aqueous solutions as borate and boric acid,can have potential impacts on the ecological environment.Accurate measurement of residual boron content in flowback fluids is crucial for mitigating its adverse effects and facilitating the reuse of treated liquids.This study employs the mannitol acid-base neutralization titration method,utilizing a mixed indicator of methyl red,bromothymol blue,and phenol red in ethanol,to determine the boron content in hydraulic fracturing flowback fluids.The experimental results indicate a recovery rate of 99.60％to 100.50％for actual samples,with a standard deviation of approximately 1％,demonstrating the accuracy and reliability of this method.
