求翻譯 本文采用直接沉淀法制備了Ag3PO4可見光光催化劑,系統(tǒng)的研究了Ag3PO4光降解甲基橙過程中外加金屬離子（Zn2+、Cu2+、Fe3+、Ag+）以及金屬離子濃度對(duì)光催化性能的影響。結(jié)果顯示，在各種金屬離子中，Cu2+,Zn2+降低了Ag3PO4降解甲基橙的光催化性能，而Fe3+、Ag+則提高了Ag3PO4的光催化性能；且當(dāng)Fe3+用量為2.03mg時(shí)，其對(duì)Ag3PO4光降解性能的提高效果最佳，當(dāng)Ag+用量為22.5mg時(shí)，其對(duì)Ag3PO4光降解性能的提高效果最佳。因此金屬離子對(duì)Ag3PO4的光催化性能有不同的影響。 |

The effets of additional metal ions (Zn2+、Cu2+、Fe3+、Ag+) and its concentrations to photocatalytic performance in the process of photocatalytic degradation of methyl orange by using Ag3PO4 were systematically investigated in this paper due to the preparation of Ag3PO4 visible light photocatalyst based on direct precipitation method. The results showed that, in various kinds metal ions, Cu2+ and Zn2+ had reduced the photocatalytic performance of methyl orange degraded, while Fe3+ and Ag+ had increased the photocatalytic performance, moreover, when the concentration of Fe3+ and Ag+ were 2.03mg and 22.5mg separately, it would obtain the best effect of Ag3PO4 photocatalytic degradation. Therefore, it would has different effects for different kinds of metal ions to Ag3PO4 photocatalytic degradation. |
