La présente invention concerne un procédé de captation de complexes organosiliciés en phase gazeuse ou liquide sur un solide contenant au moins 80% poids d'alumine après calcination à 1000.degree.C. L'alumine présente un volume poreux total supérieur à 30 ml/100g, une fraction du volume poreux située da ns les pores dont le diamètre est supérieur ou égal à 70 .ANG. supérieur à 10 ml/100g et une surface spécifique supérieure à 10 m2/g.
