Water Purification from Metal Ions with Modified Polypropylene Non-Woven Fabric Membrane

The adsorption of thorium ion was investigated in this study by a modified polymer adsorbent in which polypropylene is a substrate and modifying monomers, including acrylonitrile and acrylic acid. Adsorption condition was investigated, including temperature ۲۵-۵۵ œC and pH ۱-۱۰ and residence time ۱-۵ h to obtain the highest percentage of adsorption. As a result, the maximum adsorption capacity was ۵۹.۱ (mg/g). Also, the adsorption test was performed continuously in the fixed bed column.The output concentration starts to increase after ۳۳ minutes, and the column is wholly saturated after ۸۷ minutes.
