| 摘 要： | 选择西南某地正电荷发育的弱酸性粘土TY4作为吸附介质,加5%Ca(OH)2作为添加剂制作模拟屏障,用模拟核废液对介质做动态淋滤实验,得出了铀浓度随流量、pH值的变化曲线。实验结果表明,随高度增加屏障的吸附性能增大,渗透系数减小。屏障在pH为11和9附近时吸附效果较强。 |

| Abstract: | The TY4 clay which has a lot of positive charge with weak acidity somewhere in Southwest China was chosen.A dynamic experiment was deliberately designed to establish the curve of uranium's density related to flux and pH after appending 5% Ca(OH)2 as adsorption material to make simulating poles.The experimental results showed that the capability of adsorption was reinforced with increasing height and the average penetration coefficient was reduced.The pole's adsorption capability was reinforced when the pH was near 11 and 9. |
