Development and Characterization of Novel Hybrid Materials Formed from Poly(2-aminophenyl disulfide)@Silica Gel for Dye Adsorption Application

Abstract

Poly(2-aminophenyl disulfide)@silica gel (P2APDS@SiO2), a new hybrid adsorbent, was successfully prepared using the in situ polymerization method and the product was analyzed by XRD, TEM, TGA, FTIR and BET techniques. Furthermore, this investigation also included a comprehensive study of the effect of the silica gel on the electrochemical performance of the hybrid nanomaterial based on P2APDS employing cyclic voltammetry. Moreover, to determine methylene blue (MB) adsorption, the effective parameters of the adsorption process, including the concentration, pH and temperature, were investigated. The results indicated that the maximum amount of MB adsorption on the fabricated hybrid material occurred at pH 6.7 with a capacity of 109.82 mg·g−1. Furthermore, P2APDS@SiO2 is interesting for the elimination of dyes because of its recyclability and high adsorption capacity.
