Description
In nature, magnesium compounds are distributed in the form of such minerals as dolomite, magnesite, serpentinite, brucite, and in the form of such solutions as sea and ocean waters, salt lakes, bischofite. The main popular magnesium compounds are its chloride, hydroxide, and oxide. The most common technology for obtaining magnesium hydroxide is based on the action of alkaline reagents on solutions of magnesium. However, the technology has significant drawbacks. The main issue is that magnesium hydroxide cannot be obtained free of impurity metal ions, and the sediment itself has an extremely low filtration rate from the solution in which it is formed.
Magnesium hydroxide is an excellent sorbent collector for the ions of most metals, so it is possible to utilize this property of absorption of magnesium hydroxide to produce other highly pure compounds, for medicine and pharmacopeia. This paper investigates the processes of alkaline hydrolysis of magnesium chloride and the formation of magnesium hydroxide sediment, the kinetics of processes, as well as the properties of sediments. Empirical formulas for sediment production parameters with a high filtration coefficient that exceeds the known values of 1·106have been derived. The study reported here hasrevealed the possibility of obtaining in a relatively simple way highly pure chloride, hydroxide, and magnesium oxide, sodium chlorides, potassium, calcium, in which the impurity 3d metals content does not exceed the value as a percentage of (1‒4)·10-7. Due to the properties of highly pure magnesium compounds to the sorption of metal ions, it is possible to create reference samples of chemical elements for the needs of metrology. For example, to create MR phantoms to verify measurements and check the operation of magnetic resonance imaging (MRI) in medical institutions. Especially pure magnesium hydroxide can be used for instrumental methods of analytical chemistry (X-ray fluorescent, neutron-activation methods) when fabricating chemical references for testing laboratories.
