Abstract

L'invention décrit un procédé de préparation d'un gel comprenant un constituant actif. On traite une solution d'alimentation, contenant un composé ou une espèce minérale et un constituant actif, pour provoquer une gélification afin de former un gel minéral dans la totalité duquel le constituant actif est distribué. Le constituant actif peut être un composé pharmaceutiquement actif, un pesticide, un herbicide, une toxine pouvant inhiber la croissance dans un milieu aquatique ou un algicide ou un précurseur de l'un de ces composés.
