- MnO2/Cellulose fiber Nanocomposites were synthesized for removal of toxaphene.
- Response surface methodology to analyze the data.
- High maximum adsorption capacities were obtained for removal of toxaphene.
The MnO2/Cellulose fiber Nanocomposites have been prepared via the microwave-assisted hydrothermal method. The characteristic structure of MnO2/Cellulose fiber Nanocomposites was analyzed using X-ray diffraction, photoluminescence and UV-vis spectra, Transmission electron Microscopy, N2 adsorption-desorption and Scanning electron microscopy instrumental techniques. BET surface area and crystallite size values of MnO2/cellulose fiber nanocomposites have been found as 87.064Â m2/g and 70.0Â nm, respectively. Response Surface Methodology (RSM) has been used for adsorption of Insecticide compound such as Toxaphene by prepared adsorbent. MnO2/Cellulose fiber Nanocomposites shows maximum removal of 96.5% at initial Toxaphene concentration of 5.0Â mg/L, pH 3 and adsorbent dose of 5.0Â g/L. Kinetic and equilibrium data follow pseudo-second order and Langmuir isotherm model, respectively. Adsorption capacity of MnO2/Cellulose fiber Nanocomposites has been found to be 5.465Â mg/g.
