Times Cited Count：0 Percentile：0(Environmental Sciences)In this work, hydrothermal leaching was applied to simulated soils (clay minerals vermiculite, montmorillonite, kaolinite) and actual soils (Terunuma, Japan) to generate organic acids with the objective to develop an additive-free screening method for determination of Sr in soil. Stable strontium (SrCl
) was adsorbed onto soils for study and ten organic acids were evaluated for leaching Sr from simulated soils under hydrothermal conditions (120 to 200
C) at concentrations up to 0.3 M. For strontium-adsorbed vermiculite (Sr-V), 0.1 M citric acid was found to be effective for leaching Sr at 150C and 1 h treatment time. Based on these results, the formation of organic acids from organic matter in Terunuma soil was studied. Hydrothermal treatment of Terunuma soil produced a maximum amount of organic acids at 200C and 0.5 h reaction time. To confirm the possibility for leaching of Sr from Terunuma soil, strontium-adsorbed Terunuma soil (Sr-S) was studied. For Sr-S, hydrothermal treatment at 200C for 0.5 h reaction time allowed 40% of the Sr to be leached at room temperature, thus demonstrating an additive-free method for screening of Sr in soil. The additive-free hydrothermal leaching method avoids calcination of solids in the first step of chemical analysis and has application to both routine monitoring of metals in soils and to emergency situations.

Times Cited Count：0 Percentile：0.01(Chemistry, Inorganic & Nuclear)The radioactivities in the environmental samples are analyzed to monitor the nuclear power facilities. The pretreatment of radioactive nuclides of alpha and beta emitters in the environmental samples is performed with acid to decompose organic matter and extract object nuclide such as 
Sr, U and Pu. However, the pretreatment methods are time-consuming and used many concentrated acid solutions that are unsafe and hazardous. Therefore, we develop to the new pretreatment method using supercritical water instead of acid. Hydrothermal pretreatment of soils (Andosols) from Ibaraki prefecture (Japan) was used to improve methods for monitoring radioactive Sr and U. Calcined samples were pretreated with subcritical or supercritical water (SCW) followed by extraction with 0.5 M HNO
solutions. With SCW pretreatment, recoveries of Sr and U were 70% and 40%, respectively. Experimental recoveries obtained can be described by a linear relationship in water density. The proposed method is robust and can lower environmental burden of routine analytical protocols.

Radioactivity concentration in environmental sample such as leaf, seaweed has been measured through chemical separation with organic matter decomposition and extraction of target element. However, the usual chemical treatment could affect worker's health, chemical hood and surrounding environment by usage of chemical regent. On the other hand, supercritical water reaction could decompose organic matter without health and environmental hazard caused by the regent. Therefore, we have tried to apply the supercritical water reaction to radioactivity analysis of environmental samples. In this research, organic matter content and strontium concentration in environmental sample were compared with between before and after the reaction. The organic matters were highly decomposed with the water reaction at higher temperature and for longer reaction time. However the strontium was not extracted into solution after the reaction.

The conventional pretreatment of radioactive nuclides of beta-ray emitters (Sr) and alpha-ray sources (U, 
Pu, 
Pu, 
Am) in the environmental and bioassay samples is performed with much chemical regents to mineralize of organic matters and extract target nuclides. The mineralization of organic matter is both time-consuming and inefficient and it requires a large quantity of acid reagents that are toxic. On the other hand, supercritical water (SCW) can decompose organic matters without chemical regents. Therefore, in this research, the SCW was applied for decomposition of environmental and bioassay samples.
