چکیده
|
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 25-55 °c and ph 1-10 and residence time 1-5 h to obtain the highest percentage of adsorption. as a result, the maximum adsorption capacity was 59.1 (mg/g). also, the adsorption test was performed continuously in the fixed bed column.the output concentration starts to increase after 33 minutes, and the column is wholly saturated after 87 minutes.
