Bactericidal properties of magnesium hydroxide nanodispersions and intelligent feedback platforms

Abstract In this study, 3-(Trimethoxysilyl) propyl methacrylate was used as a modifier for surface modification of magnesium hydroxide to prepare magnesium hydroxide nanodispersions. Among them, the magnesium in magnesium hydroxide comes from the brine of the Charkhan Salt Lake. Magnesium hydroxide nanodispersions are well dispersed in water, and the UV transmittance of aqueous nanodispersions with a powder mass ratio of 10 wt% can reach more than 60%. Aqueous-phase magnesium hydroxide nanodispersions were used for the preparation of a bactericidal solution, which had a good scavenging effect on Escherichia coli, providing a new idea for the application of magnesium hydroxide in the field of bactericides.
