How many times can silica gel be regenerated
WebSilica gels are classified into three types: regular, intermediate, and low density gels. Regular density silica gel is prepared in an acid medium and has a high surface area (e.g., 750 m 2 g −1). Intermediate and low density silica gels have low surface areas (300–350 and 100–200 m 2 g −1, respectively). WebThe present invention is concerned a process for the regeneration of the spent silica gel used in chromatography and for any other kind of silica. The process comprises 5 main steps,...
