摘要：推导了二氧化硫在纯水和柠檬酸钠溶液中稳态渗透通量表达式，研究了ＳＯ２在液膜中的促进传递机理，用局部平衡理论及非平衡边界层理论推导了ＳＯ２通过膜液的渗透模型；考虑了溶液粘度、溶液的非理想性及盐效应等物理化学性质和热力学性质等因素对ＳＯ２渗透行为的影响，并将实验所得数据与模拟值进行了比较。
The expressions of steady state SO 2 permeation fluxes across pure water and aqueous sodium citrate were derived. The facilitated transport mechanism of SO 2 in the liquid membrane was proposed. The equilibrium approximation and nonequilibrium boundary layer approximation (NEBLA) were used to obtain the permeation flux of SO 2 through membrane solution. The physicochemical and thermodynamical properties of SO 2 liquid membranes system varied with temperature and other factors were considered. Compared with experimental data, the state of NEBLA can better describe the transport behavior of SO 2 than that of equilibrium approximation.
