Preparation, properties, and applications of 8-hydroxyquinoline immobilized chelate

Nature and Estimation of Functional Groups on Solid Surfaces

“…The dye was dissolved off the silica gel in alkaline solutions. Using a similar approach, Hill [664] and Sugawara et al [665] reduced the nitro groups of p-nitrobenzoylchloride-treated SIL-(CHz)3-NH2 with sodium dithionite, and coupled with 8-hydroxyquinoline after diazotation:…”

Immobilized Chloroxine as a Preconcentration Reagent for Atomic Absorption Spectrometry

“…These values are higher than those required for oxine; Malamas et al (5) reported that a pH value of 6.5 gave maximum chelation for Cu 2+ , Zn 2+ , Co 2+ , Pb 2+ , Ni 2+ , and Cd 2+ , and Sugawara et al (10) reported pH values of 2-5 for maximum preconcentration. The pH values were also higher than those used for preconcentration with sulphoxine (7).…”

Calculation of Solubility of Oxyquinolinates

“…Variations in the substituents on the quinoline rings affect its luminescence properties [24]. Oxine is also widely used for analytical and separation purposes [25]- [27].…”
