“…Table 1 reports the comparison of analytical performance of the proposed method with previously reported methods for the assay of VA in different matrices. Among FI-CL methods reported in the literature (25)(26)(27)(28)(29)(30)(31), the proposed method has low detection limit, wide linearity and high injection throughput except lucigenin-Brij-35-CL (27), tris(2,2′-bipyridyl)Ru(II)-Ce(IV)-CL (25) and Ce(IV)-Na2SO3-CL (29) methods respectively and in most of these methods, high concentration of CL reagents and PMT voltage have been employed comparatively.…”

“…In flow-mode, DPA coupled with luminol CL reaction has many applications for the determination of different analytes in several samples (21,24). Several flow injection-CL (FI-CL) and FI-UV/Vis-spectrophotometric methods have been described in the literature for the quantitative measurements of VA (retinol) in different matrices (12,13,(25)(26)(27)(28)(29)(30)(31). The analytical figures of merit, optimum experimental parameters and their applications for all these methods have been described in Table 1.…”

In this paper, a chemiluminescence (CL) method is proposed for retinol determination by combining flow injection (FI) methodology. The CL reaction is based on the oxidation of luminol by diperiodatoargentate(III) (DPA) in the presence of retinol. Under the optimum conditions, the relative CL intensity was linear to the concentration of retinol over the range 5.0310 23 -14 mg L 21 (y5347.26x12.5944, R 2 50.9999, n58) with limit of detection (LOD) of 1.5310 23 mg L 21 (S/N53) and limit of quantification (LOQ) of 5.0310 23 mg L 21 (S/N510). The relative standard deviation (RSD) was from 1.04-3.4% over the range studied and injection throughputs of 150 h 21 . The method was satisfactorily applied to retinol in pharmaceutical formulation samples. The samples were saponified and extracted with liquid-liquid extraction using ether as an extractant. The possible CL mechanism is supported by CL and UV-visible spectrophotometric studies.

“…Ag NPs (~5 nm in diameter) were obtained according to the literature [26]. First, 100 mL of a solution containing AgNO 3 and Na 3 C 6 H 5 O 7 , both in a concentration of 0.25 mmol•L −1 , was prepared and stirred for 30 s. Then, 3 mL 1.0 mmol•L −1 solution of NaBH 4 (freshly prepared) was added quickly to the mixture. The solution immediately turned to yellow and was stirred for 60 s and then stored in refrigerator at 4˚C before use.…”

It was found that silver nanoparticles could strongly enhance the chemiluminescence (CL) of the luminol-KIO 4 system in the presence of Co 2+ . The most intensive CL signals were obtained with silver nanoparticles in diameter of 22 nm. The studies of UV-visible spectra and CL spectra were carried out to explore the possible CL enhancement mechanism. Moreover, the influences of 17 amino acids and 25 organic compounds on the luminol-KIO 4 -Co 2+ -Ag NPs CL system were studied by a flow injection procedure, which led to an effective method to detect these compounds. KeywordsFlow Injection, Luminol, Chemiluminescence, Silver Nanoparticle * Corresponding author. nanoparticles, especially metal nanoparticles, as catalysts for the chemiluminescence system has attracted considerable interest.Recently, the combination of nanoparticles with chemiluminescence has attracted substantial interest because the noble metal nanoparticles have been found to participate in CL reactions as a catalyst, reductant, luminophor, and energy acceptor [20] [21]. For example, Lin et al. [22] [23] have reported that metal nanoparticles can enhance the CL of the luminol-H 2 O 2 and NaHCO 3 -H 2 O 2 system. Cui's group applied noble metal nanoparticles to the CL reactions of lucigenin and potassium permanganate system [24] [25].In this study, we examined the response of Ag NPs for CL intensity of the luminol-KIO 4 -Co 2+ system. The prepared Ag NPs displayed much stronger catalytic activity in presence of Co 2+ on the luminol CL than single Ag NPs or Co 2+ . The effects of reaction conditions on the CL intensity were examined. Moreover, the possible enhancement mechanism of Ag NPs on luminol-KIO 4 -Co 2+ CL reaction was investigated in terms of the UVvisible and CL spectra in detail. In addition, the influences of amino acids and organic compounds on the luminol-KIO 4 -Co 2+ -Ag NPs CL system were reported in extension. Experimental Section Reagents and MaterialsAll chemicals and reagents were analytically pure and used without further purification, and the deionized and triple-distilled water was used throughout.A 2.5 × 10 −2 mol•L −1 stock solution of luminol (3-aminophthalhydrazide) was prepared by dissolving luminol (Fluka) in 0.1 mol•L −1 sodium hydroxide solution. Working solutions of luminol were prepared by diluting the stock solution with water. The 1.0 × 10 −2 mol•L −1 stock solution of periodate was prepared by dissolving 0.23 g KIO 4 (Shanghai, China) in 0.01 mol•L −1 sodium hydroxide solution, and stored in a brown bottle to avoid photochemical decomposition. Silver nitrate, trisodium citrate, hydroborate, amino acids and organics were obtained from Sinopharm Group Chemical Reagent Co. Ltd. (Shanghai, China).
