农林废弃物吸附剂对Cu^(2+)的吸附性能研究

Study on the adsorption of Cu^(2+) by agricultural and forestry wastes

给出一个集物理化学、分析化学于一体的综合性实验.实验制备出生物质吸附剂,并运用红外光谱仪分析其结构;考察吸附剂对Cu2+的吸附条件,研究其吸附机理.该实验涉及物理化学的表面吸附原理和分析化学中分析方法的运用、大型仪器的使用,以及一些数据处理方法,既锻炼了学生的动手操作能力,又提高了学生对实验数据的处理分析能力.

The paper introduces a comprehensive experiment of physical chemistry and analytical chemistry. This experiment prepared biomass adsorben which structures are analyzed by fourier transfrom infrared spectroscopy （FT-IR）.The adsorption conditions on copper of the adsorbent is investigated,and absorption mechanism is studied.The experiment involved the surface adsorption principle of physical chemistry, the application of analysis methods, the use of large-scale instruments and some ways of dealing with data,which can both culturestudents＇ practice ability,and improve their processing and analysis power of the experiment data.
