Abstract
Anionic clays, layered double hydroxides, are natural or synthetic materials that have special properties, especially regarding their retention capacity. This quality is due to their lamellar structure, formed by parallel planes, different molecules of interest could be intercalated between them. This allows the use of anionic clays in various fields such as: chemical industry, food industry, pharmaceutical and medical industry, as well as environmental protection. The paper presents important aspects regarding their preparation possibilities.
