Residual TLC silica gel: recuperation process, characterization and application
Maia, Juciely Carvalho; Batista, Francisco Samuel da Cunha Lima; Fernandes, Diógenes Gaudêncio da Silva; Rios, Maria Alexsandra de SousaThe use of silica gel intensively in chemical laboratories has a high cost, and generate a significant amount of solid waste contaminated with organic compounds. In this sense, the search for effective methods to reduce the impacts that this material can cause to the environment, has been a motivating factor for many researchers, since its use has grown extensively in scientific research segment. So, the presen...
Utilização da sílica gel recuperada como fase estacionária para purificação do ...
Maia, Juciely Carvalho; Nobre, Francisco Xavier; Freitas, Alessandra Ribeiro; Vieira, Ewerton Gomes; Rios, Maria Alexsandra de SousaOne of the main purposes of Green Chemistry is the development and application of chemical processes to reduce or eliminate the use and generation of hazardous substances to the environment. Thus, considering the importance of environmentally safe methods, this work presents an alternative method of silica gel recovery aiming its use in chromatography column. In order to verify the efficiency of the procedure, ...
