(a) ΔRGB alterations of the [AuCl₄]⁻ and Glu mixture in the absence and presence of heavy metal ions (0.77 M) after microwave reaction. Each value is an average of four parallel measurements, and the error bars are shown. (b) The nine heavy metal ions were quantitatively distinguished by the PCA method.
