THE APPLICATION OF PRINCIPAL COMPONENT REGRESSION ON SIMULTANEOUS MULTICOMPONENT DETERMINATIONS THROUGH A SINGLE CATALYTIC KINETIC RUN

摘要

The kinetic behaviors of CrfVI) and W(VI), which catalyze a common indicator reaction between H_2O_2 and I~-, were studied. A new concept, 'Rate Spectrum', is proposed. The two catalysis can be determined simultaneously by analyzing the rate spectra of their mixtures as the rate spectra of each catalyst are linearly independent. Principal Component Regression (PCR) was used to analyze the rate spectra of the mixtures of Cr and W, and in this way the two ions were determined simultaneously through a single kinetic run.
