Polarographic behaviour and determination of nitrofurantoin, chloramphenicol and related compounds Morales, Alfonso; Toral Ponce, María; Richter Duk, Pablo (1984)The polarographic behaviour of nitrofurantoin and chloramphenicol have been studied in pyridine - formic acid buffer and tetramethylammonium chloride solution at pH 4.3. The E<inf>1/2</inf> versus pH and iym ...
