研究了病死猪热解炭化物对水中Cu~(2+)的去除效果,并借助扫描电子显微镜、X射线光谱仪及傅里叶红外光谱仪等分析手段对病死猪热解得到的炭化物理化学性质进行了表征,分析了其微观结构及官能团.结果发现,病死猪热解炭化物内部具有大量孔状结构,表面出现了PO3-4等结构.最后,利用热解得到的炭化物对水中的Cu~(2+)进行处理研究,考察了初始p H值、反应温度、吸附时间等对水中Cu~(2+)去除效果的影响.结果表明,病死猪热解炭化物对水中Cu~(2+)的吸附效果较好,最佳初始p H值为5.0,温度的升高有利于热解炭化物对Cu~(2+)的去除.通过对实验数据进行动力学及吸附等温线分析,发现实验中使用的病死猪热解炭化物对Cu~(2+)的吸附动力学数据符合准二级吸附动力学方程,Langmuir模型能较好地描述Cu~(2+)在猪热解炭化物上的吸附行为.
The effect of pyrolyzate on the Cu 2+ removal in diseased pigs was studied. The physicochemical properties of carbonized charcoals were characterized by scanning electron microscopy, X-ray spectroscopy and Fourier transform infrared spectroscopy , And its microstructure and functional groups were analyzed.The results showed that a large number of porous structures were found in the pyrolyzed carbonized pigs and the structure of PO3-4 appeared on the surface.Finally, The effects of initial p H value, reaction temperature and adsorption time on the removal of Cu 2+ in water were investigated.The results showed that the sorption effect of pyrolyzate on the Cu 2+ in water was higher than that on the Cu 2+ removal in water Good, the best initial p H value of 5.0, the temperature is conducive to pyrolysis of carbonized Cu 2+ removal.According to the experimental data of kinetic and adsorption isotherm analysis found that the experimental use of dead pigs The kinetic data of the adsorption of Cu 2+ on pyrolytic carbonates are in accordance with the quasi-second order adsorption kinetics equation. The Langmuir model can well describe the adsorption behavior of Cu 2+ on porcine pyrolytic carbon compounds.
