Adsorption of Dyes on Magnesium Hydroxide

The basic adsorption regularities of water-soluble dyes (acid, direct and basic) on magnesium hydroxide were studied.

Zusammenfassung:	The basic adsorption regularities of water-soluble dyes (acid, direct and basic) on magnesium hydroxide were studied. The dyes were shown to be better adsorbed on magnesium hydroxide precipitated from an aqueous solution of magnesium sulphate than on magnesium hydroxide precipitated from aqueous solutions of magnesium chloride. It was demonstrated thermodynamically that magnesium hydroxide is an effective adsorbent of acid and direct dyes.
