Feldspars, a type of important and prevalent primary mineral in soils, play a significant role in the migration of radioactive strontium in the environment. Nevertheless, there are rare studies on strontium adsorption on feldspars. This work presents a study on the interaction between strontium and K-feldspar at the solid-water interface. The effects of environmental factors were evaluated using batch experiments with ⁹⁰Sr tracer. Surface complexation contributed to the chemical adsorption of strontium in the slightly acidic condition.

锶在钾长石-水界面的吸附

长石是土壤中一种重要且普遍的原生矿物，在放射性锶在环境中的迁移中发挥着重要作用。然而，关于长石吸附锶的研究很少。这项工作介绍了锶和钾长石在固水界面的相互作用的研究。^使用90 Sr 示踪剂的批量实验评估环境因素的影响。表面络合有助于锶在微酸性条件下的化学吸附。
