为了研究功能剂量的去离子水、温度和腐植酸(HA)对土壤中铀(U)的吸附,开展批次实验。土壤按颗粒粒子大小分为砂土(>63μM),粉砂(>2~<63μM)和粘土(<2μM)。结构分析显示,土壤主要是砂、粉砂以及丰富的粘土的混合。X射线衍射分析表明,粘土中石英和蒙脱石从2.8%到5%。实验结果表明:高丰度粘土和低含砂量土壤 In order to study functional dosages of deionized water, temperature and humic acid (HA) adsorption of uranium (U) in the soil, a batch experiment was conducted. Soil is divided into sand (> 63 μM), silt (> 2 ~ <63 μM) and clay (<2 μM) by particle size. Structural analysis shows that the soil is mainly composed of sand, silt and abundant clay. X-ray diffraction analysis showed that the silica and montmorillonite in the clay range from 2.8% to 5%. Experimental results show that: high abundance of clay and low sand content of soil
