Adsorption Study of Eriochrome Black T Dye on Polyacrylonitrile Chromium molybdate Composite
Polyacrylonitrile chromium(III) molybdate composite has been synthesized by mixing polyacrylonitrile into inorganic material chromium molybdate. The physicochemical properties of this material were determined using X-ray diffractometer system (XRD), infrared (IR) and thermal analysis (TGA and DTA)....

| description | Polyacrylonitrile chromium(III) molybdate composite has been synthesized by mixing polyacrylonitrile into inorganic material chromium molybdate. The physicochemical properties of this material were determined using X-ray diffractometer system (XRD), infrared (IR) and thermal analysis (TGA and DTA). The adsorption studies were carried out under various parameters, such as pH, adsorbent dosage, contact time, and initial dye concentration. The experimental results show that the percentage of adsorption increases with an increase in the adsorbent dosage. The maximum adsorption occurred at the pH value of 2.45 The equilibrium uptake was increased with an increase in the initial dye concentration in solution. Adsorption kinetic data were properly fitted with the pseudo-second-order kinetic model. The experimental isotherms data were analyzed using Langmuir and Freundlich isotherm equations. The best fit was obtained by the Langmuir model with high correlation coefficients (
