摘要：

The horseradish peroxidase-mediated dimerization of hydroxyphenylpropionic acid can be used to measure hydrogen peroxide in seawater. The method was optimized and interferences investigated, and the method was then adapted to the measurement of choline in seawater. The enzyme choline oxidase is used specifically to oxidize choline to produce betaine and H2O2, and the latter is measured. Possible interferences with this method were investigated, and choline was measured in coastal seawater, where it varied from 0 to 45 nM. © 1990.
