We study microbubbles (MBs) in aqueous electrolyte solutions and show that increasing the salt concentration slows down the kinetics of MB dissolution. We modified the Epstein-Plesset theory and experimented with NaCl aqueous solutions to estimate the MB effective surface charge and to compare it with predictions from the modified Poisson-Boltzmann theory. Our results reveal a mechanism responsible for the change in the dissolution of MBs in aqueous electrolyte solutions, with implications for emerging fields ranging from physics of solutions to soft and biological matter.
我们研究了水性电解质溶液中的微泡（MBs），结果表明，增加盐浓度会减缓微泡的溶解动力学。我们修正了爱泼斯坦-普莱塞特理论，并对氯化钠水溶液进行了实验，以估算微泡的有效表面电荷，并将其与修正后的泊松-玻尔兹曼理论的预测结果进行比较。我们的研究结果揭示了一种导致微泡在水性电解质溶液中溶解变化的机制，这对从溶液物理学到软物质和生物物质等新兴领域都有影响。
