ABSTRACT. ABSTRACT. ABSTRACT. ABSTRACT. The kinetics of oxidation of 2-amino-1-butanol (AB) by diperiodatoargentate(III) (DPA) has been studied spectrophotometrically in alkaline media in the temperature range 288. ]. Increasing ionic strength of the media decreased the rate. The rate and equilibrium constants involved in the mechanism were calculated. There is good agreement between the observed and calculated rate constants under varying experimental conditions. The activation parameters for the slow step were computed and discussed. Thermodynamic quantities were also determined.

“…DPA was prepared by oxidizing Ag(I) in the presence of KIO 4 as described elsewhere [8]: the mixture of 8 g of KOH and 3.42 g of NaIO 4 in 100 mL of water along with 1.36 g AgNO 3 was heated just to boiling and 3 g of K 2 S 2 O 8 was added in several small amounts with stirring. The mixture was then allowed to cool.…”

“…42 In brief, the mixture solution of silver nitrate (AgNO3, 1.36 g), potassium periodate (KIO4, 3.24 g), sodium persulfate (Na2S2O8, 3.0 g), and potassium hydroxide (KOH, 8.0 g) was prepared in 200 mL water and heated to boiling for about 40 min on a hotplate (Cenco Instrument MIJ N.V., Breda, the Netherlands) with constant stirring. The DPA complex obtained was dried and stored at room temperature and was found stable for several months.…”

Flow Injection-Chemiluminescence Method for Determination of Hyoscine Butylbromide Using Silver(III) as Oxidizing Agent

et al. 2017

Diperiodatoargentate(III) (DPA)/silver(III) complex, [Ag(HIO6)2] 5-, in sulfuric acid medium has been used to determine hyoscine butylbromide (HBB) by flow injection (FI) coupled with chemiluminescence (CL) detector. A linear standard curve between the CL intensity and concentration range from 0.005 to 20 mg L -1 was obtained. The determination coefficient (R 2 ), limit of detection (3s × blank), relative standard deviation (RSD) for 0.5 mg L -1 HBB and analytical throughput were 0.9992 (n = 8), 5 × 10 -4 mg L -1 , 1.5% (n = 10) and 160 injections h -1 , respectively. The developed method was applied for the determination of HBB in pharmaceutical formulations with recoveries from 92 ± 4 to 108 ± 3%. For comparison, a spectrophotometric method was used and the results obtained by both methods were in good agreement at a 95% confidence level. The effect of key chemical and physical variables (reagent concentration, flow rate, sample volume, PMT voltage) and interfering species (pharmaceutical excipients and inorganic ions) on the determination of HBB was examined. The possible CL mechanism of HBB on silver(III) complex in sulfuric acid medium was also discussed in brief.Keywords Chemiluminescence, flow injection analysis, silver(III) complex, hyoscine butylbromide, pharmaceutical formulations
