Abstract (en)
[origin: EP2014358A1] The invention discloses a method for the synthesis of hydrotalcite-like adsorbent which is in particular suitable for the adsorption of sulfur-containing anions, e.g. in the purification of drinking water. The method comprises mixing an aqueous aluminium source and aqueous magnesium source with an alkaline and/or soda containing solution under high shear agitation. As the aluminium source is used an extract derived from the extraction of clays with strong mineral acids in the production of bleaching earth. The product can be easily separated and directly used as an adsorbent for different anions.
