    To further investigate the detection performance of the Nesslers reagent method, standard curves for NH 3 were prepared at pH 1 and pH 13 (Figure 3a,b). At both pH, strong linear relationships were established between absorbance at 420 nm and the concentration of ammonia in the solution ( R 2 = 0.9995 and 0.9999, respectively).
