AB  - Dual determination of nitrite and iron was proposed by using a single greener 
      sequential injection (SI) spectrophotometric system employing a simple single 
      aqueous extract from Areca catechu Linn. The extract served as a natural reagent 
      to replace N-(1-naphthyl)ethylenediamine (NED) of the Griess reagent with nitrite 
      and 1,10-phenanthroline with iron. The color products possessed analytical 
      wavelengths at 430 and 560 nm, respectively. Conditions for the SI procedure were 
      optimized using a univariate experimental design. Calibration ranges were up to 
      5.0 mg L(-1) and 10.0 mg L(-1) with limits of detection (LODs) of 0.04 mg L(-1) 
      and 0.05 mg L(-1) for nitrite and iron(iii), respectively, and relative standard 
      deviations (RSDs) being less than 3%. Recoveries of spiked standard nitrite and 
      iron(iii) at 0.3 mg L(-1) and 0.5 mg L(-1) in water samples were 88 to 104% and 
      84 to 109%, respectively. The developed method successfully achieved dual 
      determination of nitrite and total iron agreeing at a 95% confidence level with 
      the reference methods of the conventional Griess assay and flame atomic 
      absorption spectrometry (FAAS), respectively. The proposed method utilized 
      locally available material from plants and serves the UN-SDGs.
