The MnO/Cellulose fiber Nanocomposites have been prepared via the microwave-assisted hydrothermal method. The characteristic structure of MnO/Cellulose fiber Nanocomposites was analyzed using X-ray diffraction, photoluminescence and UV-vis spectra, Transmission electron Microscopy, N adsorption-desorption and Scanning electron microscopy instrumental techniques. BET surface area and crystallite size values of MnO/cellulose fiber nanocomposites have been found as 87.064m/g and 70.0nm, respectively. Response Surface Methodology (RSM) has been used for adsorption of Insecticide compound such as Toxaphene by prepared adsorbent. MnO/Cellulose fiber Nanocomposites shows maximum removal of 96.5% at initial Toxaphene concentration of 5.0mg/L, pH 3 and adsorbent dose of 5.0g/L. Kinetic and equilibrium data follow pseudo-second order and Langmuir isotherm model, respectively. Adsorption capacity of MnO/Cellulose fiber Nanocomposites has been found to be 5.465mg/g.
通过微波辅助水热法制备了MnO/纤维素纤维纳米复合材料。利用X射线衍射、光致发光和紫外可见光谱、透射电子显微镜、N吸附-脱附和扫描电子显微镜等仪器技术对MnO/纤维素纤维纳米复合材料的特征结构进行了分析。发现MnO/纤维素纤维纳米复合材料的BET表面积和微晶尺寸值分别为87.064m/g和70.0nm。响应面法(RSM)已用于所制备的吸附剂对杀虫剂化合物毒杀芬的吸附。MnO/纤维素纤维纳米复合材料在初始毒杀芬浓度为5.0mg/L、pH值为3、吸附剂剂量为5.0g/L时,最大去除率为96.5%。动力学和平衡数据分别遵循准二级和朗缪尔等温线模型。发现MnO/纤维素纤维纳米复合材料的吸附容量为5.465mg/g。
