被引用回数：341 パーセンタイル：99.58(Engineering, Environmental)The pH dependent Cu(II) and Pd(II) ions detection and removal efficiency was investigated using ligand embedded mesoporous adsorbent. The adsorbent permits to fast and specific visualization of Cu(II) and Pd(II) ions detection and removal from aqueous media via a colorimetric signal visible to the naked eye. The adsorbent showed very high adsorption capacity (182.39 and 172.53 mg/g for Cu(II) and Pd(II), respectively) and adsorption uptake on the adsorbent reaching equilibrium was also very rapid with extreme selectivity in ionic competition.

Arsenic; Detection, Management Strategies and Health Effects, p.117 - 129, 2014/00
Arsenic has evoked concerns related to the environmental and human health issues for decades. In recent years, the concern has been relocated to the front position as more of the world's population relies on groundwater as a source of clean drinking water, which is reported to be contaminated due to the elevated level of arsenic. The surface processes such as precipitation, dissolution, adsorption, and desorption have been controlled by geochemical parameters, such as pH, Eh, ionic composition, and mineral type, and determine the mobility characteristics of arsenic and the abundance in any given location. The chapter will provide a critical review of the issues related to the distribution and abundance of arsenic in the soils and plants.

加速器質量分析(AMS)を活用したSrの新たな分析方法では、従来の
線検出法よりも優れた検出限界(1/10の
0.1mBq)を達成した。本研究では、様々な性状をもつ環境試料に対するAMS法の適用性を実証するため、本研究ではチョルノービリ原子力発電所の冷却水供給池から採取した不純物を多く含む水試料を分析した。本報告会では水試料のSr/
Sr原子数比(線検出器とICP-MSによる評価)、予想検出限界、分析方法を報告する。今後は、水試料のSr濃度(Bq/L)に関してAMS法と線検出法とで比較することで、AMS法の適応性を示す予定である。
