To investigate the migration behavior of Sr (strontium) in granite, a rough-walled single fracture of granite was prepared with the self-built rock splitting apparatus. Surface roughness angle and hydraulic aperture of the fracture were measured by 3D laser scanning and fluid flow experiment, respectively. The sorption and desorption breakthrough experiments of Sr in the single fracture were conducted at different flow rates and initial concentrates of Sr, and the important transport parameters were derived by fitting the BTCs and DPCs. The results suggested that the sorption of Sr onto the fracture surface was a linear and reversible ion-exchange process, unaffected by the variation of flow rate and initial concentrate of Sr.

为了研究锶（锶）在花岗岩中的迁移行为，用自建的岩石劈裂仪制备了花岗岩的单壁粗糙裂缝。通过3D激光扫描和流体流动实验分别测量了裂缝的表面粗糙度角和水力孔径。在不同流速和Sr初始浓度下，对Sr在单个裂缝中的吸附和解吸突破实验进行了研究，并通过拟合BTC和DPC得出了重要的输运参数。结果表明，Sr在断裂面上的吸附是线性且可逆的离子交换过程，不受流速和初始浓度的变化的影响。锶。
