    摘要:
    以m(ZVI)∶m(Cu)=10∶1制備了ZVI/Cu(鐵/銅)雙金屬顆粒,并以ZVI/Cu雙金屬作為催化 劑活化雙氧水(H2O2),通過產生的強氧化劑羥基自由基(·OH)降解偶氮染料甲基橙.通過對 ZVI/Cu雙金 屬進行表征,觀察其表面形貌及微觀結構.對比ZVI、Cu和ZVI/Cu雙金屬活化 H2O2 降解甲基橙的去除率隨 時間的變化,發現ZVI/Cu雙金屬具有較強的活化 H2O2 降解甲基橙的能力.研究了ZVI/Cu雙金屬顆粒的投 加量、雙氧水的濃度和pH 值對甲基橙去除率的影響,并對試驗參數進行了優化.結果表明,在甲基橙初始質 量濃度為50mg·L-1、ZVI/Cu雙金屬投加量為3g·L-1、H2O2 濃度為2.0mmol·L-1、pH 值為4.0的條 件下,反應進行60min甲基橙去除率可達到80.1%.
