We measured barium attachment and detachment fluxes from and to barite crystal surfaces in solutions with [Ba]/[SO] ratios from 0.06 to 52. The doping of Ba in the initial experimental solutions enabled us to measure unidirectional fluxes near solubility equilibrium (/ ≈ 1.0) in batch reactors. Both attachment and detachment fluxes increase with [Ba]/[SO] ratios. As expected, since the solutions were near solubility equilibrium (), the attachment and detachment fluxes were nearly equal.

富含 137Ba 的溶液中 Ba 附着和脱离重晶石表面的通量，其 [Ba2+]/[SO42−] 比率接近溶解度平衡

我们测量了 [Ba]/[SO] 比为 0.06 至 52 的溶液中钡在重晶石晶体表面的附着和脱离通量。初始实验溶液中 Ba 的掺杂使我们能够测量接近溶解度平衡的单向通量 (/ ≈ 1.0）在间歇式反应器中。附着通量和分离通量均随 [Ba]/[SO] 比率的增加而增加。正如预期的那样，由于溶液接近溶解度平衡 ()，因此附着通量和分离通量几乎相等。
