In this study, the potential of 8-Hydroxyquinoline grafted SBA-15 to extract of Cu2+ cations from aqueous solutions was investigated. SBA-15 nanoporous silica was chemically grafted with 8-Hydroxyquinoline groupsaccording to the procedure in the literature. The presence of organic groups in the silica framework was demonstrated by FTIR spectrum. The grafted product showed th...
This investigation was carried out to develop a convenient alternative method for examining the performance and determining the dead time of a stopped-flow fluorometer. We examined the kinetics for the formation of the fluorescent Mg2+-8-hydroxyquinoline chelate in aqueous solutions. The reversible association of the Mg2+ ion with 8-hydroxyquinoline is a second-order process whose on and off ra...
