Simultaneous determination of dimetridazole and furazolidone in feed-premixes by D.C. Polarography.
A polarographic method has been proposed by which dimetridazole and furazolidone can be determined in combination in feed-premixes in a single determination. The sample is treated with DMF to facilitate the dissolution of dimetridazole and furazolidone. Britton-Robinson buffer of pH = 6.8 is added and the solution is polarographed at the dropping mercury electrode vs. SCE. The waves are sufficiently separated to allow quantitative determination. The standard-addition method is used. The method is simple and very fast.
