Development of vapor generation–spectrophotometric detection system for selective determination of trace amount of sulfide in water
Year: 2010
Abstract:
A continuous flow vapor generation system for the determination of sulfide at low levels in aqueous samples based on hydrogen sulfide prevaporation and spectrophotometric detection has been developed. In a modified ...
Silica-coated magnetic NiFe2O4 nanoparticlessupported H3PW12O40; synthesis, preparation, and application as an efficient, magnetic, green catalyst for one-pot synthesis of tetrahydrobenzo[b]pyran and pyrano[2,3-c]pyrazole derivatives
Year: 2016
Abstract:
A powerful, magnetic, supported, acid catalyst, NiFe2O4@SiO2–H3PW12O40, was prepared by chemical support of Keggin (H3PW12O40) heteropolyacid (HPA) on silica-coated NiFe2O4 magnetic nanoparticles. XRD, TEM, SEM, VSM, and ...
