实验过程

A copper (II) acetate monohydrate solution was prepared by dissolving 89.8 g of copper acetate salt in 1.125 l of deionized water at 70° C. 300 g of the zeolitic material of CE 1.4 was then added to this solution. An ion-exchange reaction between the NH4+-form of the zeolitic material and the copper ions was carried out by agitating the slurry at 70° C. for 1.5 hours. The pH was between 4.8 and 4.5 during the reaction. The resulting mixture was then filtered, washed until the filtrate had a conductivity of <200 microSiemens/cm, which indicated that substantially no soluble or free copper remained in the sample, and the washed sample was dried at 90° C. The obtained Cu containing material comprised Cu at 2.4% by weight and Na at 104 ppm. The SiO2:Al2O3 was 30:1.
