摘要
在经典通量模型H-P方程的基础上,建立了有机溶剂通过纳滤膜通量(J)的数学模型。通过实验考察了溶剂黏度(μ)、摩尔体积(Vm)和溶解度参数(δ2)对溶剂J的影响,验证了所建模型的准确性和适用范围。结果表明,Vm和δ2是影响有机溶剂纳滤膜J的重要参数。对纯溶剂,该模型能较好的解释其传递规律,与实验有较好的一致性;对混合溶剂,该模型与实验数据的吻合较差,说明混合溶剂J的影响因素较复杂。
A model of organic solvent flux through nanofiltration membranes, based on the classic H-P model, has been derived. The effects of solvent viscosity （μ）, molecular volume （Vm） and solubility parameter （δ^2） on solvent flux （J） were investigated in order to probe the veracity and applicable range of the model. The results showed that Vm and δ^2 are the major parameters affecting the flux of organic solvents. For pure solvents, the model was found to be in close accord with experiment and provided a good description of flux transfer phenomena. For mixed solvents however, the model is not consistent with experimental data, indicating that the dependence of solvent flux on the other parameters is far more complicated.
