摘要
通过静态吸附实验,研究了K+在烟草叶梗上的吸附性能,考察了粒径大小、pH值、温度、K+浓度、阴离子、共存物质等诸因素对吸附的影响。结果表明,粒径大小、pH值、温度、K+浓度、阴离子、共存物质对吸附均有明显影响;吸附热力学过程可用Freund lich等温吸附模型描述。
The adsorption properties of potassium ion on the stem of tobacco , as well as the influence of the diameter of the particles, pH value ,temperature, K^＋ concentration ,anionic ,substance together with K^＋ on adsorption have been studied by static method. The results indicated that they all have a great effect on adsorption capacity. Adsorption isotherms of the stem of tobacco for K^＋ obey the Freundlich＇ s equation.
