在生物界中,经过地球化学的一系列合成和积累,微生物对动植物遗骸经过分解转化形成包括腐殖酸等有机物质,广泛存在于水体、土壤、煤矿中.有效消除水体中腐殖酸是控制水体微污染的关键环节,MnO2纳米线因对其具有良好的吸附效果,可强化去除水中腐殖酸而受到关注.本文针对当前国内外学者对MnO2纳米线合成及吸附腐殖酸的研究现状,阐述了MnO2纳米线的合成方法,分析腐殖酸在水合表面的吸附行为,并展望了MnO2纳米线的研究与应用方向.%In the biological world,through a series of synthesis and accumulation of geochemistry,microorganisms have decomposed and transformed the remains of plants and animals, including humic acid and other organic substances, which are widely found in water,soil and coal mines.The effective elimination of humic acid in water is the key to control the micropollution of water.The MnO2 nanowire has good adsorption effect, which can strengthen the removal of humic acid in water.In view of the current domestic and foreign scholars'study to MnO2 nanowires, the research development of synthesis and adsorption of humic acid on the synthesis methods of MnO2 nanowires, analysis the adsorption behavior of humic acid in water surface and prospects the direction of the research and application of MnO2 nanowires were described.
