제목 Adsorption of methylene blue by one pot synthesized CuS nanocomposite with reduced graphene oxide
초록 Nowadays, dyes are used in different sector, like dyeing industries, color paper mill, color printing, textile, cosmetics companies are using dyes for the demand of people. Unfortunately this one covers a big portion to pollute the environment as the effluents from textile, leather, food contains dyes. Adsorption is an excellent method to remove the dye from the solutions. Using a high surface area and low cost adsorbent, a promising result can be obtaine. Based on this theory, a low cost one pot method has been chosen to synthesize CuS nanoparticles (np) in combination with reduced graphene oxide (RGO).  
In this work, RGO-CuS nanocomposites (nc) was synthesized by hydrothermally treatment of GO and copper acetate with thiourea. The obtained product was analyzed by FE-SEM, EDS and XRD. After the confirmation of the formation of this product, it was used as an adsorbent of methylene blue (MB), where MB is adsorbate. RGO-CuS nc reached its equilibrium state faster than bare CuS np. For 20ppm MB, equilibrium adsorption capacity, qe is 16.9 and 14.2 mg/g for bare CuS np and RGO-CuS nc, respectively. More characterization of the product and the adsorption experiment is going on.
