Synthesis of 15-, 17- and 19-membered thiacrown ether functionalized composite SBA-16 adsorbents for selective recovery of silver (Ag+) ions |
초록 |
Dihydroxy functionalized 15-, 17- and 19-membered thiacrown-4 ethers (thia-CEs) were synthesized by intermolecular cyclization of bulky epoxides with 1,2-benzenedithiol. The bulky epoxides were synthesized from etherification of bromoalkenes with penderol then epoxidation of their alkenes. Preparations of thia-CEs were optimized by changing the metal templates, reactant concentrations, reaction solvents, time, and temperature. Each thia-CE will be immobilized into 3-(chloropropyl)triethoxysilane functionalized mesoporous silica to enhance the recyclability of the adsorbents. Batch adsorption and desorption (acid treatment) experiments will be performed. These composite adsorbents have the potential as successful Ag+ ion recovery.
