چکیده
A method has beed developed for the analysts of cobalt In natural waters by catlon-exchange llquld chromatography udng lumlnol chemllumlnescence detectlon. Cobalt can be detemrkred dlrectty In freshwater samples on 500-pL samples wlth a detectlon llmlt of 20 pmol/kg; larger samples provide proportknately bwer detectlon #mlts. Seawater samples can be analyzed on lOOmL samples followlng APDC solvent extractkn; the detectlon lknlt of thk method Is 5 pmol/kg. The precidon of the method Is f5%. The method should also be applkaMe to the analysts of V, Cu, and Fe In natural waters. Equipment Is low In cost and transportable and can be used In the field.

Selective determination of ubiquinone in human plasma by HPLC with chemiluminescence reaction based on the redox cycle of quinone.
Ubiquinone is an important biologically active compound in the living body. The determination of ubiquinone in human plasma is useful for the investigation of bioavailability of ubiquinone and for early diagnosis of several diseases. Therefore, we developed a high-performance liquid chromatography (HPLC) with chemiluminescence detection method for the analysis of ubiquinone in plasma samples. T...
متن کاملChemiluminescence Determination of Atropine using Luminol-Hemin-H2O2 System
A sensitive and fast chemiluminescence (CL) method has been described for the direct determination of atropine. The method is based on the quenching effect of atropine on the CL signals of the luminol– H2O2 reaction catalyzed by hemin in an alkaline medium. Hemin could strongly enhance the chemiluminescence of the luminol–H2O2 system. The luminophor of the luminol–H2O2–hemin CL system was ident...

متن کاملComparison between Amperometric and Chemiluminescence methods in detection and dosimetry of cobalt-60 gamma ray emission
Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...
متن کاملSimultaneous determination of N,N-dimethylaniline and phenol in wastewater by high-performance liquid chromatography with chemiluminescence detection.
A method using HPLC-CL linkage was developed for simultaneous determination of N,N-dimethylaniline and phenol in wastewater, based on the strong sensitive chemiluminescence of the luminol-K3Fe(CN)6 systems in alkaline medium. The separation was carried out on a Hypersil ODS column with a mobile phase of ethanol-0.01% triethylamine (2:1, v/v). The linear ranges for N,N-dimethylaniline determinat...
