Nagaraja, P and Kumar, MSH and Mallikarjuna, NN (2002) Dapsone a new diazotizing reagent for the spectrophotometric determination of nitrite in waste and natural water samples. In: Annali di Chimica, 92 (1-2). pp. 127-134.Full text not available from this repository.
A new diazotizing reagent for the spectrophotometric determination of nitrite is described. The method is based on diazotization-coupling reaction between dapsone and phloroglucinol in hydrochloric acid medium. The reactions were conducted at room temperature, the molor absorptivity at 425 nm is 4.28 x 10(4) 1 Mol, (1)cm(-1) and was stable for 50 h. Beer's law was obeyed in the nitrite range of 0.008 - 1.0 mug ml(-1). Tolerance limits were tested for 33 species. The method has been found to be applicable for the determination of nitrite in natural and wastewater.
