In this work, the analytical properties of immobilized cation ERIA in the silk fibroin matrix were studied using spectroscopic and spectrometric methods for the determination of Cd (II) ion by sorption-spectrophotometric methods. Optimal conditions for complex formation and immobilization processes were selected. Based on cation ERIA immobilized on silk fibroin matrix, a lower detection limit with high accuracy parameters, low detection limit, reproducible results, simple and fast method was developed for the determination of Cd (II) ion.
