“…Surveys of many organic compounds for enhancement of CL emission in the luminol-H202 system (22)(23)(24)(25) have not resulted in any analytical applications. Organic complexants such as EDTA (26), 8-hydroxyquinoline (27), and amino acids (28) have been determined by their inhibition of CL from metal-enhanced systems.…”

“…They demonstrate the system's applicability to the determination of thorium, vanadium, and iodide. They also have developed similar automated concentration "stats" which used optical absorbance ("absorptiostat") (140), dual polarized amperiometric ("biamperostat") (141) and luminescence intensity (luminostat) (142) monitoring. They applied these methods for the analyses of iodine and molybdenum (140, 141), catalase and copper (140, 142) and manganese (14l).…”

“…It is well-known that the CL reaction of luminol with H 2 O 2 catalyzed by Cu(II) ion is carried out in a strong alkaline medium [21]. For this reason, the NaOH concentration to dissolve the luminol was kept constant (Table 1) to assure an alkaline pH.…”

A simple and sensitive method has been proposed for the amikacin sulphate determination. It is based on the inhibition of the chemiluminescence (CL) emission generated from the oxidation of luminol in alkaline medium by H2O2 catalyzed by Cu(II), due to the interaction caused by amikacin, which forms a robust complex with the catalyst. The optimization of the experimental and instrumental variables affecting this CL inhibition effect has been carried out using statistical models, based on the application of two-level full factorial and Box-Behnken designs. The performance characteristics of the proposed method have been established, showing that the method is efficient to determine amikacin sulphate in the linear range of 9.89-20 mg/L with a detection limit of 2.97 mg/L. It has been successfully applied to the amikacin sulphate determination in pharmaceutical formulations.
