Abstract
The invention relates to a method for rapidly distinguishing potassium chloride particles and sodium chloride particles. The method is characterized in that a sodium tetraphenyl borate solution is prepared by utilizing an organic solvent, the surface of a to-be-detected particle is wetted by utilizing the sodium tetraphenyl borate solution, and the potassium chloride particles and the sodium chloride particles can be distinguished by observing whether the liquid on the surface of the particle is turbid or not or whether needle-shaped precipitates are generated on the surface of the particle or not, wherein the particle with needle-shaped attachments on the surface is the potassium chloride particle; the particle with a liquid on the surface being turbid and having white precipitates is the potassium chloride particle. The sodium tetraphenyl borate alcohol solution reacts with the potassium chloride to generate stable white precipitates which are attached onto the surface of the potassium chloride, so that the potassium chloride particles and the sodium chloride particles can be rapidly distinguished, and a great amount of work for grinding a sheet and judging the potassium chloride and the sodium chloride according to the difference of the refractive index when the coarse potassium chloride and the coarse sodium chloride are distinguished in the identification of a phase can be avoided.
