This paper investigates the effectiveness of copper and zinc ions an economical and environmentally friendly method for inhibiting the scaling of drinking water, using the method of rapid controlled precipitation (RCP). The results indicated that zinc ions and copper ions, at low concentrations, were highly efficient inhibitors in a 300 mL solution (calcium ion concentration of 126.5 mg/L). To produce an inhibition efficiency of 100% (in 70 min), the concentration of the copper ion was 0.9 mg/L and that of the zinc ion was 0.4 mg/L. The analysis by SEM and infrared absorption spectrometry showed that copper and zinc ions could affect the calcium carbonate germination and change the crystal morphology, which indicated that copper and zinc ions had participated in the composition of the crystal; however, the quantity of copper or zinc ion in the precipitate was so small that it was difficult to observe them.
本研究采用快速控制沉淀（RCP）法，考察了铜、锌离子作为一种经济、环保的方法，抑制饮用水结垢的效果。结果表明，在 300mL 溶液中（钙离子浓度为 126.5mg/L），低浓度的锌离子和铜离子是高效的抑制剂。为了达到 100%的抑制效率（70min 内），铜离子的浓度为 0.9mg/L，锌离子的浓度为 0.4mg/L。SEM 和红外吸收光谱分析表明，铜、锌离子可以影响碳酸钙的成核，改变晶体形态，这表明铜、锌离子参与了晶体的组成；然而，沉淀物中铜或锌离子的数量很少，难以观察到。
