“…This concept was first explored almost three decades ago, when silica with a layer of cromia 33 or of several other metals 34 was evaluated for normal phase chromatography. However, the complicated preparation procedures meant that this approach never met with much success.…”

“…Earlier there were several attempts to obtain chromatographic supports with different surface chemistry: one of first was the group of Aue and co-workers [181] who used volatile chlorides of several metals (AlCl 3 , FeCl 3 , SnCl 4 ) and later CrCl 3 [182] for the reaction with silica silanols. The bonded metals were hydrolyzed and used in HPLC as "metal oxides with silica geometry".…”

“…Outros grupos de pesquisadores também vêm aplicando suportes de óxidos metálicos mistos para as mesmas finalidades. Os primeiros a sugerirem a utilização de óxidos mistos como fases estacionárias na modalidade de fase normal da CLAE foram Aue e Wickramanyake 63 . Estes autores produziram partículas de sílica de 10 µm com camadas de crômia ligadas à sua superfície.…”

“…Basicamente, o procedimento é o mesmo realizado para o preparo de óxidos mistos com alcóxidos metálicos, porém, substituindo o grupo alcóxido por cloretos 59,60 . A reação pode também acontecer em temperaturas elevadas, superiores a 500 ºC, para depositar cloretos de óxidos metálicos na sílica, obtendo materiais praticamente puros e sem necessidade de estágios de lavagem com solventes orgânicos para remoção de resíduos 63 .…”
