【摘要】 研究了水溶液中两种不同粒径的烟草对甘油的吸附作用。测定了两种不同粒径烟草在不同温度下的吸附等温线。考察了温度、酸度和乙醇对吸附的影响。结果表明:在稀溶液中吸附甘油符合Langmuir模型;烟草对甘油的吸附具有吸附速度快,温度影响小的特点。更多还原

【Abstract】 The adsorptive properties of glycerol on tobacco, as well as the influences of temperature、pH、time and solvent on adsorption ability were studied. The adsorption isotherms of two different tobacco were determined. The results show that adsorbing capacity of tobacco for glycerol is high, rate of adsorption is fast.更多还原
