Fungi of the type Aspergillus sp. were immobilized on a cellulosic resin and used as a biosorbent for the on-line preconcentration and separation of Pt(IV) ions prior to their chemiluminescent determination via flow injection analysis. Biosorption and elution conditions were optimized, and the results compared to biosorbents based on the use of Chlorella vulgaris algae and Saccharomyces cerevisiae...
A new flow-injection chemiluminescence method (FI-CL) was developed for the determination of trace amounts of Pt(IV). The method is based on the quenching effect of the analyte on CL emission generated by lucigenin in alkaline solution. Application of a column filled with an algae Chlorella vulgaris immobilized on Cellex-T resin allowed to preconcentrate and separate the Pt(IV) ions from complex environmental...
A novel flow-injection chemiluminescent (CL) method of determination of trace amounts of Pt(IV) based on its catalytic effect on the reaction of oxidation of luminol in alkaline solution is proposed. The method employs on-line separation of analyte on the column containing green algae Chlorella vulgaris immobilized on Cellex-T support. The application of biosorption process for elimination of interferences...
