为了支持使用KURION介质处理福岛第一核电站高污染水的去污系统的设计和运行，电力工业中央研究所紧急开展了多种研究和开发计划，以支持使用三种KURION介质（H，AGH和SMZ）填充柱的去污系统的运行。由于福岛第一核电站的污染水中含有海水和油，因此，通过批次类型仔细研究了海盐和溶解油对Cs吸附行为的影响。溶液中海盐的浓度在0.0和3.4重量%之间变化。KURION赫歇尔石在海水中对Cs的吸附能力下降到纯水中的1/10左右，但仍有足够的吸附能力去除污染水体中的Cs。由于溶解油在海水中的溶解度较低，其影响可以忽略不计。建立了可用于估算铯在海水中吸附的Langmuir型吸附等温式。
To support the design and operation of the decontamination system using KURION media for the treatment of highly contaminated water accumulated in Fukushima Daiichi Nuclear Power Station, Central Research Institute of Electric Power Industry has urgently carried out many kinds of research and development programs to support the operation of the decontamination system using columns filled with three kinds of KURION media (H, AGH and SMZ). Since the contaminated water at Fukushima Daiichi Nuclear Power Station contained seawater and oil, the effects of sea salt and dissolved oil on Cs adsorption behavior were examined closely by batch type. The concentration of sea salt in the solutions was varied between 0.0 and 3.4 wt%. The Cs adsorption capacity of KURION herschelite in seawater decreased to nearly 1/10th of that in pure water, but it was still concluded that herschelite has sufficient adsorption capacity to remove Cs from the contaminated water. The effect of dissolved oil could be ignored because of its low solubility in seawater. Langmuir-type adsorption isotherm equations, which can be applied for estimating Cs adsorption in sea salt containing water, were developed.
