Answer to Problem 1DE
Solution: The test for the detection and the quantification of the chemicals involved in fracking operation.
Explanation of Solution
The chemicals involved in fracking operations are hydrochloric acid, sodium chloride, ethylene glycol, borate salt, water soluble gelling agents such as guar gum, citric acid, methanol, isopropanol and methane.
Amongst the above chemicals, hydrochloric acid and citric acid are acidic in nature, sodium chloride is a salt, ethanol and isopropanol are volatile alcohols and the guar gum and ethylene glycol are the viscosity modifier.
The test for the detection of the acids is to check for the
The volatile alcohols are detected and quantified by gas chromatography.
The gelling agents are detected by comparing the viscosity of the sample solution and the regular domestic water. These are quantified by the UV-visible spectroscopy.
The concentrations of all the chemicals are determined to ensure the source is from the fracking operations, since the determination of some chemicals does not ensure the exact source of impurity.
For the detection and the quantification of the chemicals involved in fracking operations, the test based on their physical properties should be designed.
