Rapid Spectrophotometric Determination of Trace Amounts of Nitrate-Nitrogen Using Dapsone and α-Naphthol
A simple, rapid and sensitive spectrophotometric method has been developed for the trace determination of nitrite using Dapsone and α-Naphthol. The proposed method is based on the diazotization of Dapsone followed by coupling with α-Naphthol in sodium hydroxide medium to give an intense pink coloure...
