Estimation of Æmax (Absorption maximum of ascorbic acid) To determine the absorption maximum, standard solutions of ascorbic acid in concentration of 30 ppm. were prepared. Scanning of the complex in a wavelength range from 350 nm to 650 nm showed a maximum. absorbance (Æmax) at 521 nm as shown in figure 1.
