摘要:
本发明公开了一种锌铝二元水滑石及其作为光催化材料降解甲基紫的应用,所述水滑石化学通式为[Zn2+1-xAl3+x(OH)2](CO32-)x/2·mH2O],其中x为Al3+/[Al3++Zn2+]的摩尔比,0.2≤x≤0.33,m为结晶水数量,2≤m≤6;本发明所述锌铝二元水滑石的双羟基复合氢氧化物用于催化降解染料废水中甲基紫,反应条件温和,染料去除率高,催化降解后的材料易回收利用。
摘要(英):
The invention relates to zinc-aluminum binary hydrotalcite and an application thereof as a photocatalytic material used for degrading methyl violet. The hydrotalcite has a chemical general formula of [Zn<2+>1-xAl<3+>x(OH)2](CO3<2->)x/2.mH2O], wherein x is the molar ratio of Al<3+>/[Al<3+>+Zn<2+>], x is no smaller than 0.2 and no greater than 0.33, m is the number of crystal water, and m is no smaller than 2 and no greater than 6. When dihydroxyl composite hydroxide of zinc-aluminum binary hydrotalcite provided by the invention is used for catalyzing the degradation of methyl violet in dye wastewater, the reaction condition is mild, the dye removal rate is high, and materials can easily be recycled after degradation.
