除了第3天附近的弯曲点外，Zn²⁺的日释放量在前7天逐渐增加，然后在7-21天缓慢下降，并在几天后呈上升趋势。总的来说，Zn²⁺的释放量在0.13和0.36 mg L^-1之间变化。如图10b所示，Zn样品的重量损失随时间稳定增加，确定了纯Zn在AP中的溶解。

In the first 7 d the daily release amount of Zn²⁺ gradually increases except for a flexion point around day 3, then decreases slowly during 7–21 d, and inversely witness an upward trend in the few days later. Overall, the release amount of Zn²⁺ varied between 0.13 and 0.36 mg L⁻¹. As depicted in Fig. 10b, the weight loss of Zn samples increases steadily with time, ascertaining the dissolution of pure Zn in the AP.
