Facile Synthesis of Nanostructured Dentritic Polythiophene Nickel Composite and Its Application in the Adsorptive Removal of Methylene Blue

Authors(3) :-Abhishek Kumar Mishra, Ishwar Das, Namita Rani Agrawal

Polythiophene nickel nanocomposite was electrochemically synthesized from solution containing thiophene, perchloric acid and nickel chloride in acetonitrile medium and its application as adsorbent for the removal of Methylene blue (MB) dye was investigated. Polythiophene nickel composite (PTh-Ni composite), showed excellent water dispersibility. Polymer aggregates were characterized by transmission electron microscopy (TEM), Powder X- ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), electrical conductivity and fractal dimension calculation. Electrical conductivity was found to increase with increase in nickel chloride concentration. Particles of the polythiophenes nickel composite were showed average size < 5 nm. Optimum dosage of adsorbent were determined and found to be1.5 gL-1 for PTh-Ni composite. Adsorption capacity (Q) is found to increase with increase in pH values. Experimental data were tested using Langmuir, Frendlich and Temkin models, and data were best followed by Freundlich model at 30oC. The maximum adsorption capacity (Qm) for PTh-Ni composite was found to be 384.61 mg/g. Various kinetic equations were applied to kinetic data and were best followed by pseudo-second-order kinetic model. The thermodynamic parameters such as change in enthalpy (ΔH°), entropy (ΔS°), and free energy (ΔG°) were calculated. The adsorption is spontaneous and endothermic in nature. Adsorption/ desorption results are also reported.
