A picrate ion-selective electrode without inner reference solution and based on bis(triphenylphosphoranylidene)ammonium picrate dissolved in 2-nitrophenyloctyl ether was constructed and its characteristics assessed. With respect to reducing sugar determination in Port wine, a tubular electrode based

In this work, p-hydrorqbenxoic acid hydraxide has been used as a reagent to determine reducing sugars using flow-injection analysis with photometric detection (410 nm). Parameters such as the temperature, alkalinity, reactor length, injection volume, flows and reagent concentration were examined for
