摘要：
A Co(II) chelate membrane from a poly(vinyl alcohol)/poly(allyl amine) blend was synthesized. As an intermediate step the blend membrane was modified to a Schiff-base type. Structures of blend and Schiff-base membrane were confirmed by the FTi.r. subtraction method. Differential scanning calorimetry thermograms of blend and Schiff-base membranes showed that the glass transition temperature (T(g)) ranges between 40 and 50-degrees-C. Co(II) content in chelate membrane was determined by electron dispersive X-ray spectroscopy, elemental analysis and thermogravimetric analysis and ranged between 9.82 and 15.75 wt%. As the membrane becomes chelate with Co(II), the density increases as measured by a density gradient column.
