✦ Synopsis


An automatic procedure for the determination of nitroprusside has been developed. It is based on the strong quenching effect of the nitroprusside on the photochemical reaction between phloxin and ethylenediaminetetraacetic acid. The proposed flow-injection method allows the fluorimetric determination of nitroprusside in the range (6 \times 10^{-6}-7) (\times 10^{-5} \mathrm{M}) with a sampling frequency of 35 samples per hour. The method has been applied to the determination of the nitroprusside in human serum and pharmaceutical preparations. 1995 Academic Press, Inc.

A highly selective flow-injection system was developed for the determination of methanol. The system consisted of three immobilized enzymes with luminol chemiluminescence detection. First, methanol was oxidized in the presence of alcohol ozidase to yield formaldehyde and hydrogen peroxide. The hydro
