地浸采铀是为核电可持续发展提供燃料的重要途径之一。表面活性剂在地浸中具有增高矿层渗透性、提高铀浸出率的潜在功效。为了研究表面活性剂在地浸采铀中的应用,验证表面活性剂的加入是否会影响地浸生产中树脂的性能,采用柱实验研究了OP-10、FSO、LVA、LF221等几种非离子表面活性剂及其复配物对地浸生产液中铀的树脂吸附和淋洗的影响。结果表明,生产液中加入50-100mg·L~(?1)上述不同表面活性剂和复配物均对铀的树脂吸附没有产生影响,吸附曲线、树脂吸附容量、树脂的循环利用与不含表面活性剂的结果相一致。表面活性剂的加入能够提高淋洗液中铀含量的峰值,降低淋洗后树脂中残余铀含量,从而可以...

Background: The In situ leaching (ISL) of uranium mining is an important method to nuclear reactors for sustainable utilization of nuclear energy. Surfactants have their potential role in the increasing permeability of ore bed and the leaching rate of uranium in ISL. Purpose: The aim is to study the application of surfactants in ISL and identify whether the addition of surfactants have any effect on the resin property. Method: The influence of several surfactants such as OP-10, FSO, LVA, LF221 and their complexes on resin adsorption and elution...
