The determination of nitrobenzene compounds by Zinc reduction-optimization-naphthyl ethylene-diamine dihydrochloride spectrophotometric method was optimized .The operation steps were simplified , a water volume of 8.0 mL was used instead of 4.0 mL,a 20 mm cuvette was employed to take place of the 10 mm cu-vette.The method detection limit decreased from recommended 0.20 mg/L to 0.05 mg/L.The laboratory detec-tion limit was 0.042 mg/L.The determination results of standard sample meet the requirement by improved method.
