| Research Abstract |
To develop novel monitoring technique using NMR multivariate analysis for hazardous compounds in water environmental, sensitivity and accuracy of 600 MHz NMR instrument with cold probe were tested. The determination limit was estimated to be 10-40 ppm with a margin of error of 10 %. The absolute purities of 41 pesticide commercial standards were determined using qNMR. The result showed that the several standards had lower purities than the labeled values by manufacturers. In addition, qNMR spectra of about 100 hazardous compounds were stored in the database for multivariate analysis.
