How to detect the KCl content in acidic mother liquor water
Thread Content
I have an acidic mother liquor that needs to be tested for its KCl content. Seek an analysis method.
To determine the concentrations, chloride and potassium ions are measured separately; chloride can be determined by titration or ion chromatography, while potassium is determined by atomic absorption or flame photometry
For high concentrations, chemical titration can be used: sodium tetraphenylborate is employed to determine potassium – \"Chemical World\", March 1955 issue
In a solution, if potassium chloride is not the only dissolved salt, it is not appropriate to use terms related to the determination of potassium chloride; it is better to measure the concentrations of chloride ions and potassium ions separately. Method for detecting chloride ions: 1) Precipitation titration with standard silver solution； 2》Potentiometric titration of standard silver solution ； These two methods must eliminate interfering factors during chlorine determination ； 3》Ion chromatography ； 4》Chloride ion selective electrode method (low accuracy) ； Methods for detecting potassium ions: 1) Sodium tetraphenylborate titration method or gravimetric method ； 2》Ion chromatography ； 3》Potassium ion selective electrode method ； 4》Atomic absorption spectrometry ； 5》Atomic Emission Spectroscopy
