Abstract
Sulfonated porous carbon (PC-SO3H) shows enhanced Sr2+ adsorption performance in terms of removal capacity, kinetics, and selectivity.
Highlights
Nuclear power is considered a promising candidate to satisfy the increased demand for energy
The surface area for porous carbons (PC) and PC-SO3H was calculated according to the Brunauer–Emmett–Teller (BET) method, and the pore size distribution was determined from a non-local density functional theory (NLDFT) method
Sulfur and oxygen contents were shown to increase following the sulfonation of PC even though the observed sulfur composition is a bit lower than its expected value
Summary
Nuclear power is considered a promising candidate to satisfy the increased demand for energy. Adsorption is o en considered a feasible and somewhat economical method for the recovery of radioactive isotopes from liquid wastes.[7,8,9,10] Numerous studies have considered the removal of Sr2+ from aqueous environments using various adsorbents. Clay minerals such as kaolinite[11] and attapulgite[12]. Various comparative adsorption studies between the sulfonated porous carbon and non-functionalized porous carbon were investigated to highlight the performance characteristics of SO3H groups, speci cally Sr2+ adsorption, with the mechanism for ion exchange clearly demonstrated and discussed
