<br>宋体">Pervaporation membranes can be classified into organic and inorganic
<br>membranes. NaA zeolite membrane, as an inorganic membrane, has well-defined
<br>zeolitic pores with high hydrophilicity. The pore size of NaA zeolite membrane
<br>is 0.42 nm, which is larger than water molecule (~ 2.9 A) and less than most of
<br>organic molecular diameters. Therefore, the membrane shows excellent
<br>permselectivity and flux for separation of water from organics. Compared to
<br>organic membranes, the zeolite membranes have several advantages including
<br>higher permeation flux, higher separation factor and better thermal/chemical
<br>stability.<o:p></o:p></span></p>
