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

여기, 나노 임베디드 복합 막과 방사성 iodines의 효율적이 고 이온 선택적 제거에 응용 프로그램의 준비에 대 한 세부 프로토콜을 설명합니다. 시트르산 안정 금 나노 입자를 사용 하 여 (평균 직경: 13 nm) 및 셀 루 로스 아세테이트 막, 금 나노 입자 포함 셀 루 로스 아세테이트 막 (Au-캠) 조작 쉽게 있다. Au 캠에 나노 adsorbents 매우 안정적인 무기 염, 유기 분자의 높은 농도 존재 했다. 수성 해결책에서 요오드 화 이온이 조작된 막 빠르게 캡처할 수 수 있습니다. Au 캠 포함 필터 유닛, 우수한 제거 효율을 사용 하 여 여과 과정을 통해 (> 99%) 뿐으로 이온-선택적 담 결과 짧은 시간에 달성 했다. 또한, 누구나 캠 그 공연의 상당한 감소 없이 좋은 재사용 제공. 이러한 결과 현재 기술 설계 하이브리드 멤브레인을 사용 하 여 액체 폐기물에서 방사성 요오드의 대규모 오염에 대 한 유망 과정일 것 이다 제안 했다.

우리 누구나 캠 시트르산 안정제 AuNPs 및 셀 루 로스 아세테이트 막 (그림 1a)를 사용 하 여 제작에 대 한 간단한 방법을 설명 했다. Au 캠 표면은 나노 셀 룰 로스 nanofibers (그림 2)에 안정적으로 통합 했다 보여준 SEM으로 관찰 되었다. 나노 멤브레인에 투 옥 되었다 안정적으로 하지 1.0 M NaCl 등 수성 솔루션으로 지속적?...
