近年、様々 なナノと膜が吸着技術25,26,に彼らの特定の機能に基づく水質有害放射性金属や重金属を除去する開発されています。27,28,29,30,31,32,33,...

数十年、医療機関、研究施設、原子力発電所の放射性液体廃棄物の膨大な量が生成されました。これらの汚染物質は、環境および人間の健康1,2,3への明白な脅威をよくされています。特に、放射性ヨウ素は、原子力発電所事故から最も危険な要素の 1 つとして認識されます。たとえば、環境報福島とチェルノブイリ原子炉の量は、放射性のヨウ素131を含むを発表したことを示した (t1/2 = 8.02 日) と129私 (t1/2 =1570 万年) 環境にいた他の放射性核種の4,の5のそれらより大きかった。特に、これらの放射性同位元素の露出は、高吸収とひと甲状腺6にエンリッチメントで起因しました。さらに、リリースされた放射性ヨウ素は水で土壌・海水・地下水の高い容解性のための深刻な汚染を引き起こします。水溶性廃棄物7,8,9,10で放射性ヨウ素をキャプチャするため、さまざまな無機および有機性吸着剤を用いた修復プロセスの多くを行った,11,12,13,14,15,16,17,18,19,20. 高度な吸着システムの開発に多大な努力がなされて、連続流の下で満足のいく性能を示す除染方法の確立だった非常に限られました。最近では、我々 は金ナノ粒子 (結果)21,22のハイブリッド ナノ複合材料を使用して良い除去効率、イオン選択性、持続性、再利用性を示す新しい海水淡水化プロセスを報告,23。 その中で、金ナノ粒子に埋め込まれたセルロース アセテート膜 (Au-CAM) は比較した既存の吸着材の連続フロー システムの下でヨウ化物イオンの高効率脱塩を促進します。さらに、全体の手順は、医療・産業用アプリケーションで後の使用から生成された核廃棄物の処置のためのもう一つの利点は短時間で終了できます。この原稿の全体的な目標は、Au カム24の準備のためのステップバイ ステップのプロトコルを提供することです。また設計された複合膜を用いた放射性ヨウ素のイオンの捕獲のため迅速で簡便なろ過のプロセスを示します。本報告では詳細なプロトコルはナノ材料環境学研究分野での有用なアプリケーションを提供します。

an efficient method for selective desalination of radioactive iodine anions by using gold nanoparticles-embedded membrane filter

ここでは、複合膜のナノ材料に埋め込まれたおよび放射性ヨウ素の効率的かつイオンの除去への応用の準備の詳細プロトコルを示す.クエン酸安定化金ナノ粒子を用いた (平均直径: 13 nm) と酢酸セルロース膜、金ナノ粒子に埋め込まれたセルロース アセテート膜 (Au-CAM) を簡単に行った。Au カムでナノ吸着剤は無機塩および有機分子高濃度の存在下で安定性の高い.水溶液中におけるヨウ化物イオンは、この人工の膜によって急速にキャプチャできます。Au カム含むフィルター ユニット、優れた除去効率を使用してろ過プロセスを通じて (> 99%) と同様、イオン選択性海水淡水化結果が短時間で達成されました。また、Au カムは、その性能が顕著に減少することがなく再利用を提供しました。設計されたハイブリッド膜を利用した現在の技術、液体廃棄物からの放射性ヨウ素の大規模除染の有望なプロセスであることが示唆されました。

Au カム クエン酸安定化金ナノ粒子と酢酸セルロース膜 (図 1、) を使用しての作製のための簡単な方法を説明してきました。Au カムの表面は、ナノ材料がナノファイバー (図 2) に安定的に組み込まれた示した SEM で観察されました。ナノ粒子膜で投獄安定維持され、1.0 M 塩化ナトリウムなどの水溶液を継続的な?...
