查询词典 Ag

The results show that the dissolution of Ag was restrained by forming of a silver suboxide film on the surface under low oxidant concentration and atmospheric pressure conditions (e.g., in NH_3-O_2-H_2O system); when the concentration of oxidant was high enough (e.g., in NH_3-H_2O_2-H_2O system), the leaching process was carried out without forming of the film and the rate of dissolution of Ag was controlled by a step of mass transfer.

结果表明，在常压下氧化剂浓度低时(如在NH_3-O_2体系中)，浸取反应受在Ag表面上生成的氧化物膜所阻碍；而在浓度足够高的氧化剂时(如在NH_3-H_2O_2体系中)，浸取过程可在不生成氧化物膜的条件下进行，此时Ag的溶解速度受传质步骤控制。
