DETERMINATION OF NITRITE AS 4-(4-NITROBENZENAZO)-1-AMINONAPHTHALENE DYE USING OPTICAL MEMBRANES BASED ON PVC-DOS MATRIX
A study of a liquid polymeric membrane based on polyvinylchloride-dioctylsebacate (PVC-DOS) as optical membrane for the spectrophotometric and visual determination of nitrite has been done. The method relied on the formation of a purple colored 4-(4-nitrobenzenazo)-1-aminonaftalen dye in the membran...
