二硫化钼电吸附铅性能研究
Study on the Electrosorptive Performance of Molybdenum Disulfide for Lead Ions
摘要
Abstract
As a desalination technology in line with the concept of green development,Capacitive De-ionization(CDI)technology has the characteristics of energy saving and environmental protection,and research on the separation and recovery of heavy metals has increased year by year.Most of the commonly used CDI electrode materials are carbon based materials,but they have low adsorption capacity and no selectivity.In the experiment,molybdenum disulfide with flower like structure is prepared by hydrothermal method as CDI cathode material,and selective adsorption is realized by the mechanism that its sulfur rich atom can coordinate with heavy metal ions.Meanwhile,the optimal operating conditions and the cyclic stability of the electrode are explored through single factor experiments,the adsorption process is fitted by adsorption kinetics,and the adsorption mechanism is analyzed.The results show that under the optimal conditions,the adsorption capacity of the electrode for lead ion is 83.91 mg/g,and the adsorption capacity is 88.81%of the initial after four cycles,the adsorption mechanism of heavy metal ions on electrode material is the combination of physical adsorption and chemical adsorption,this electrode has potential application prospect in the treatment of heavy metal wastewater.关键词
