氧化镁因其制备简单、成本低廉而被认为是一种具有吸附功能的水净化材料。本文描述了通过溶液相路线合成均匀的Mg（OH）2纳米片。多孔MgO纳米片可以通过在400 °C下煅烧Mg（OH）2前体来获得。Mg（OH）2和MgO对典型的偶氮染料刚果红（CR）都表现出良好的吸附去除性能，该染料在水溶液中具有抗氧化和脱色的特性。因此，我们得出结论，所制造的镁化合物是有前途的材料，从水溶液中去除染料。
Magnesium oxide is believed to be a promising material with adsorption functionality for water purification due to its easy preparation and low cost. This paper describes the synthesis of uniform Mg(OH)2 nanosheets via a solution-phase route. Porous MgO nanosheets can be obtained by calcining the Mg(OH)2 precursor at 400 °C. Both Mg(OH)2 and MgO show good adsorption removal properties towards a typical azo dye Congo Red (CR), which has resistance to oxidation and decoloration in aqueous solutions. We concluded therefore that the fabricated Mg-compounds are promising materials for dye removal from aqueous solutions.
