dc.description.abstractThe application of organic dyes in industry is severely limited due to its insolubility and instability. The adsorption of organic dyes by inorganic materials to form hybrid pigment is a valid method to improve its stability, thus widening its applications in industries. A simple method for preparing stable hybrid pigment by adsorpting Acid Red 73 (AR73) on the chitosan (CTS) modified sepiolite with a SiO2 coating is explored in this work. Sepiolite modified by the CTS was used to immobilize AR73 (CTS-sep/AR73) uniformly to form a hybrid pigment. The effects of the dosage of CTS, the concentration of acetic acid (HAc) and the pH of AR73 solution for CTS-sep adsorption of AR73 were investigated. CTS-sep/AR73 was further coated with a layer of SiO2 to form the CTS-sep/AR73@SiO2 pigment, which enhanced the stabilities of the hybrid pigment. The CTS-sep/AR73@SiO2 pigment shows excellent stability in strong acid, strong alkali and anhydrous ethanol environment, along with the improved thermal ageing, intensified UV resistance, and enhanced thermal stability (more than 220 °C) which is higher than that of CTS-sep/AR73 hybrid pigment.en_GB
