In this paper, we prepared three types of porous glasses (PGs) with specific surface areas of 311.60 m(2)/g, 277.60 m(2)/g, and 231.38 m(2)/g, respectively, via borosilicate glass phase separation. These glasses were further modified with amidoxime groups (AO) using the hydroxylamine method, yielding adsorbents named 1.5-PG-AO, 2-PG-AO, and 3-PG-AO. The adsorption performance of these adsorbents under various conditions was investigated, including sorption kinetics and adsorption mechanisms. The results reveal that the number of micropores and ...
