| Abstract: | Diazo reaction was reacted from NO2- with anilinesulfonic acid, and then red dye was obtained by coupling with N -（1 -naphthyl） ethylenediamine dihydrochloride. The product was determined by solid phase spectrophotography after cation exchange resin enrichment. The sensitivity and precision were advanced comparing to liquid phase spectrophotography. The results were satisfied. |
