Characterization of the adsorbent was carried out using UV–visible diffuse reflectance spectroscopy (UV–Vis DRS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The various parameters such as pH, contact time, sorbent dosage, initial dye concentration, and dye solution temperature were investigated. The optimum photo-catalytic activity of Ag2CO3-PANI at a weight content of 50% PANI for the degradation of MB was almost 86% that is much higher than the pure Ag2CO3 and PANI. The results showed an efficient removal at pH 10.0, within 60 min, and by using 1 g L-1 Ag2CO3-PANI composite at the temperature of 32˚C. The kinetic and equilibrium data fit into pseudo-second-order kinetic (R2> 0.84) and Freundlich isotherm (R2> 0.99) models, respectively. Adsorption capacity (q0) calculated from Langmuir isotherm was found to be 55 mg/g. Thermodynamic studies indicated that the adsorption process was endothermic (ΔH°˃0). The adsorption/desorption experiments were carried out attaining regenerations of up to 97% from MB, using distilled water and 0.1N HCl. The composite indicated high efficiency adsorptive properties and high reusability.</p> </p></abstract><publication_date><month>10</month><day>15</day><year>2018</year></publication_date><pages><first_page>598</first_page><last_page>609</last_page></pages><publisher_item><identifier id_type="pii">gnest_02808</identifier></publisher_item><doi_data><doi>10.30955/gnj.002808</doi><timestamp>1715130860</timestamp><resource>https://journal.gnest.org/publication/gnest_02808</resource></doi_data></journal_article></journal></body></doi_batch> </div>
