抄録/ポイント： 廃水からの銀イオン(Ag+)の選択的捕捉は,同時水浄化と資源回収に有望であるが,依然として困難である。本研究では,廃棄タバコバットから活性炭(AC)上にスルフヒドリル(SH)基をグラフトし,80°C(AC-SH-80)で加熱した吸着剤をAg+除去のために設計し,高い容量(719.2mg/g)と顕著な選択性を示した。初めて,AC-SHの吸着性能は表面Sの構造-活性モードに直接関連することを報告した。吸着および還元Ag+の量の定量分析により,2つの以前に未解明のAg+取込機構を明らかにした。(i)スルフヒドリル基は大部分のAg+をAgに変換した;(ii)静電効果によりC-OとC=Oでキレート化した少量のAg+。これらのAg+変換経路から,AC-SH-80は顕著な選択性を示し,複雑なバックグラウンドを有する実際の廃水からAg+の効率的除去を実現できる。本研究は,官能基修飾材料への重金属イオンの吸着に関与する経路の新しい解釈を提供するために,Ag+捕獲プロセスにおけるSの役割を明らかにする。Copyright 2022 Elsevier B.V., Amsterdam.
