The Use of Ultrasound for Obtaining Pharmaceutical Grade Sodium Chloride
The use of ultrasound (US) in the preparation of pharmaceutical grade (PG) sodium chloride by the sampling of final product from a vacuum evaporator during the process of obtaining the “Extra” class table salt at the crystallization stage of the sodium chloride has been investigated. The US had been used: 1) for the content control of the base matter - sodium chloride in the stock – natural brine (sonoluminescent spectroscopy method).
