摘　　要：由于氢氧化镁具有较强的吸附特性,且具有活性强、缓冲性好、无腐蚀性等特点,作为一种安全、无毒的吸附剂,在环保领域有较广泛的应用。全面综述了氢氧化镁作为吸附剂在各种水质废水(包括酸性废水、印染废水、含重金属工业废水、含磷和铵城市废水)处理,以及在海(卤)水除硼和烟气脱硫等方面的应用研究。Due to the high activity, good buffer effect, security, non-corrosive and non-poisonous proper- ties, magnesium hydroxide has been widely used as an effective adsorbent for environmental protection. The applications of magnesium hydroxide used as an adsorbent for the removal of dyes, heavy metal and ammonium ions, and phosphate from wastewater, for the removal of boron from seawater or brine, for flue gas desulfurization, etc. , were comprehensively reviewed. In addition, nanometer magnesium hydroxide is a new type of inorganic material, which has many properties such as the surface effect and small size effect, and interface effect. Therefore, nanometer magnesium hydroxide has higher adsorption capacity, making it easy to get bigger promotion in the application of environmental protection. If the surface of nano-sized magnesium hydroxide is modified with different characteristic active groups, its application in the rare and expensive elements＇ extraction will be very significant.
