“…Considering the kinetic characteristics, the PO-CL method could be easily coupled to analytical systems such as flow injection analysis and HPLC. The advantage of a PO-CL is a wide pH range to carry out the oxidation and stability and high efficiency [5,6]. Here, we investigated a thioxanthone derivative as a luminophore probe for PO-CL system.…”

The chemiluminescence generated from the reaction of bis(2,4,6-trichlorophenyl) oxalate (TCPO), hydrogen peroxide and 1,4-dihydroxy-3-methyl-thioxanthone (DMT) was investigated. Effects of reacting components, solvent and concentrations of TCPO, sodium salicylate, hydrogen peroxide and DMT were studied and their optimal values were determined. In addition, the influences of b-Cyclodextrin (b-CD) on the peroxyoxalate chemiluminescence (PO-CL) system of DMT were examined at optimized condition. The results showed that the presence of b-CD causes both enhancing and quenching effects on PO-CL system of DMT based upon its concentration. The Stern-Volmer quenching constant (K q ) was evaluated as 2.32 9 10 4 M -1 (R 2 = 0.991) by creating a linear regression plot on experimentally obtained data. This study resulted in satisfactorily determination of b-CD in the range 5.0 9 10 -6 to 1.0 9 10 -4 M.

“…Reviewing the literature revealed that up to the present time, some reports have been published concerning the CL determination of pharmaceuticals using the Ru(phen) 3 2+ system, e.g. fenbufen (10), nucleic acids (11), chlorpheniramine (12), metoclopramide (13), cefprozil (14), meloxicam (15) and thiourea (16). To our surprise, there is a lack of reports concerning the CL determination of EB using the Ru(phen) 3 2+ –permanganate system.…”

Chemiluminescence (CL) detection for the determination of estrogen benzoate, using the reaction of tris(1,10-phenanthroline)ruthenium(II)-Na(2)SO(3)-permanganate, is described. This method is based on the CL reaction of estrogen benzoate (EB) with acidic potassium permanganate and tris(1,10-phenanthroline)ruthenium(II). The CL intensity is greatly enhanced when Na(2)SO(3) is added. After optimization of the different experimental parameters, a calibration graph for estrogen benzoate is linear in the range 0.05-10 µg/mL. The 3 s limit of detection is 0.024 µg/mL and the relative standard deviation was 1.3% for 1.0 µg/mL estrogen benzoate (n = 11). This proposed method was successfully applied to commercial injection samples and emulsion cosmetics. The mechanism of CL reaction was also studied.

“…A wide variety of analytical methods have been reported for determination of cephalosporins in pure form, in pharmaceutical preparations, and in biological fluids. These methods include spectrophotometry [2–5], atomic absorption spectrophotometry [6], fluorometry [7–12], liquid chromatography [13–20], Micellar electrokinetic capillary chromatography [21, 22], chemiluminescence [23–28], potentiometric [29, 30], and polarographic [31–34] methods. Kinetic spectrophotometric methods became of great interest in chemical and pharmaceutical analyses [35].…”

A simple, reliable, and sensitive kinetic spectrophotometric method was developed for determination of eight cephalosporin antibiotics, namely, Cefotaxime sodium, Cephapirin sodium, Cephradine dihydrate, Cephalexin monohydrate, Ceftazidime pentahydrate, Cefazoline sodium, Ceftriaxone sodium, and Cefuroxime sodium. The method depends on oxidation of each of studied drugs with alkaline potassium permanganate. The reaction is followed spectrophotometrically by measuring the rate of change of absorbance at 610 nm. The initial rate and fixed time (at 3 minutes) methods are utilized for construction of calibration graphs to determine the concentration of the studied drugs. The calibration graphs are linear in the concentration ranges 5–15 μg mL−1 and 5–25 μg mL−1 using the initial rate and fixed time methods, respectively. The results are validated statistically and checked through recovery studies. The method has been successfully applied for the determination of the studied cephalosporins in commercial dosage forms. Statistical comparisons of the results with the reference methods show the excellent agreement and indicate no significant difference in accuracy and precision.
