✦ Synopsis

The method developed for the determmatlon of sugars 1s based on reduction of hexacyanoferrate(II1) by simple carbohydrates m a strongly alkaline medium at elevated temperature Changes m hexacyanoferrate(II1) concentration are momtored amperometrlcally Hrlth platinum wire electrodes polarized at 200 mV Sucrose determmatlon requires on-line hydrolysis m hydrochlonc acid The detection sensltivlty for dtierent simple sugars and dlsacchandes and the influence of several mterferents were examined Sucrose and glucose were determined with a sampling rate of 40 h-' m natural samples from a sugar production process spiked with glucose
