摘要：

The objective of this study was to establish a novel method of fluorescence for the determination of cadmium using fluorescein (FR) and 1-(2-Pyridinylazo)-2-Naohthalenol (PAN). In the pH 9.75 buffer solution of the ammonia-ammonium chloride, the energy transfer between FR and the PAN can occur, which can result in the quenching of the fluorescence. The addition of Cd (II) to this system enhances the degree of quenching. This phenomenon has led to the establishment of a novel method for the determination of cadmium, which has been optimized in terms of the required experimental conditions. In t...
