✦ Synopsis
Three contmuous-flow approaches to the development of spectrophotometnc reactton-rate methods based on the use of unmobdlzed enzymes are proposed They are based on the use of an optlcal blosensor that integrates reaction and detectron m the flow cell, or reversing the flow duectlon and passmg the sample plug lteratwely through the enzyme reactor and the detector, or a cychc system that allows the sample plug to bc trapped m a clrcutt that includes the enzyme reactor and the detector A parameter was defined to compare the features of the methods developed by using these three approaches

The rate of reaction between arsenite and vanadate, catalyzed by osmium(VIII) was monitored using an automatic potentiostatic stat method. This was carried out by maintaining the preset potential of a platinum indicator electrode by addition of a 2 Â10 À3 M vanadate solution (titrant). The rate of a
