Driven by the “dual carbon control” policy, the aim is to cultivate high-quality and application-oriented new talents in the environmental field who possess an innovative spirit and practical capabilities to adapt to social demands.展开更多

In view of the constraints of experimental hours and funding, as well as the complexity of equipment operation, this paper proposes to build an experimental course model using “virtual display + actual operation” to improve the professional practice level and ability to solve complex problems of students majoring in metal materials.展开更多

The influence of various operating parameters such temperature and adsorbent dosage on the adsorption isotherms of modified sawdust was investigated. Thermodynamic parameters, namely Gibbs free energy （△GΘ）, enthalpy （△HΘ） and entropy （△SΘ） of Cu（Ⅱ） and Ni（Ⅱ） adsorption process were calculated, showing that the adsorption is a spontaneous and exothermic process. The modified extended Langmuir equation approaches provide excellent prediction of the binary adsorption. In single and binary systems, the overall adsorption data were best described by the pseudo-second order kinetic model, then the calculated values of activation energy of Cu（Ⅱ） and Ni（Ⅱ） adsorption process were 59.12 and 55.92 kJ/mol respectively. The results show that the affinity of each metal ion onto the modified sawdust surface is influenced by the presence of the other one.展开更多
