(a) UV-vis spectra of the AO II solution treated with Powder Gbm at room temperature as a function of reaction time, inset with a photograph of the AO II solution at different treating times. (b) The dependence of Ct normalized by C0 on reaction time for all four powders at room temperature. The solid lines are nonlinear fitting to the experimental data points. (c) Comparison of the AO II degradation efficiency and degradation rate for the four studied powders. (d) Comparison of the degradation capability of the present Co-based MG and other investigated ZVMs, confirming the ultrahigh reactivity of the Co-based MG in degrading the AO II solution.
