Effect and influence of sulfate ion in preparation of magnesium hydroxide by electrodeposition

As an important inorganic compound, magnesium hydroxide is widely used in flame retardants, medicine, environmental protection and other fields. Electrodeposition is an effective method for the preparation of magnesium hydroxide. The addition of sulfate ions (SO4^2-) during the process has a significant impact on the quality and performance of the product.

Significant improvements in dispersion

The addition of sulfate ions can significantly optimize the dispersion of magnesium hydroxide particles in the electrolyte. The addition of an appropriate amount of SO4^2- effectively avoids the agglomeration of magnesium hydroxide, ensures uniform dispersion of particles, and facilitates subsequent application processing. Precise control of the deposition process

The presence of SO4^2- regulates the kinetics of the electrodeposition process, affecting the deposition rate and formation of the deposited layer. Through competitive adsorption with other ions in the solution or direct participation in electrochemical reactions, sulfate ions change the growth pattern of the deposited layer and have an important impact on the structure and properties of the final deposit. Control of crystal form and purity

The appropriate amount of sulfate ions may regulate the crystal shape and crystallinity of the product by affecting the lattice growth of magnesium hydroxide. This helps to obtain magnesium hydroxide with a specific morphology and regular crystal structure, providing a material basis for applications such as catalyst carriers and adsorption materials. Effective reduction of side reactions

Sulfate ions may inhibit the occurrence of certain side reactions by stabilizing metal ions in the solution, reducing the formation of unwanted by-products, thereby improving the purity of the magnesium hydroxide product. Sulfate ions play various roles in the preparation of magnesium hydroxide by electrodeposition. By reasonably controlling the concentration of SO4^2- and electrodeposition conditions, the deposition characteristics of magnesium hydroxide can be significantly improved and materials with better properties can be obtained. This discovery provides a new optimization direction for the preparation of magnesium hydroxide and helps promote technological progress in related fields.

With the in-depth understanding of the action mechanism of sulfate ions and the continuous innovation of application technology, it is expected that more innovative results will be brought to the preparation and application of magnesium hydroxide to meet the market demand for high-performance materials.
