The gravimetric analysis of antimony(III) with oxine (8-quinolinol, Hox) was studied. The amount of antimony left in filtrate and washing solutions was corrected with the results of atomic absorption spectrometry. The weighing form, which had not been conclusive before the present study, was determined to be SbO(ox)(Hox)2. The result (purity of antimony(II) oxide: 99.84 +/- 0.05% (m/m)) of the ...

Electrogenerated chemiluminescence (ECL) can be obtained from an electrochemically oxidized highly oriented pyrolytic graphite electrode or a graphene oxide suspension in an aqueous solution containing 0.1 M NaClO(4), phosphate buffer (PBS) (pH = 7.0) and 13 mM tri-n-propylamine. Single ECL events from individual graphene oxide nanosheets can be observed. The observation of ECL in such systems ...

The electrogenerated chemiluminescence (ECL) of Ru(dp-bpy):+ (dp-bpy = 4,4’-diphenyl-2,2’bipyridine) and Ru(dp-phen):+ (dp-phen = 4,7-diphenyl-l,lO-phenanthroline) in acetonitrile and aqueous solutions was studied. The diphenyl-substituted compounds produced a more intense emission than the nonsubstituted Ru(bpy):+ Ru(dp-phen):+ m acetonitrile. The ECL efficiencies, dECL, of Ru(dp-bpy):+ and we...
