The pollution caused by synthetic painting in wastewater has become a major problem. In particular, the deprivation of methylene blue used in the painting of cellulose materials is an increasing issue of importance from wastewater. In this study, polyanyline/cavic leather waste compounds were presented as low-cost and useful adsorbents. The compounds are prepared in different mixture proportions. The chemical structures of the adsorbents have been studied with the Fourier Conversion Infrared Spectroscopy and the Surface Morphology with the Scream Electron Microscope. The pH, the amount of adsorbent, the concentration in the initial paint, the time and temperature, the effect on the methylene blue adsorption have been studied. In various temperatures, kinetic and isothermic studies have been carried out. Adsorption behavior was studied with the help of three main isoterm models. It has been found that the obtained isotherm data more match Langmuir isotherm than Freundlich isotherm. The adsorption capacity of the composite adsorbent was 105 mg/g. The highest adsorption efficiency value was 98.93%. The reaction kinetics has been shown to match the so-called second degree kinetic model.
