摘要
以Al（NO3）3、Zn（NO3）2、Mg（NO3）2为起始原料，用NH3·H2O做沉淀剂，采用非稳态共沉淀法制备锌镁铝类水滑石ZnMgAl—LDHs。并探讨了该材料对偶氮类污染物次甲基蓝的吸附性质。结果表明，温度为40％，摩尔比为Zn^2＋／Mg^2＋=1：2，浓度6×10^-6～8×10^-6mol·L^-1,用量为0．03g时，该ZnMgAl—LDHs对次甲基蓝具有较好的吸附性能。
With aluminum nitrate, zinc nitrate, magnesium nitrate as the starting raw material, using ammonia as precipitation agent. ZnMgA1-LDHs were synthesized by non steady copreci- pitation method and characterized by FTIR.The composite material is discussed dual class nitrogen pollutants adsorption properties of methylene blue. Results show that the temperature of 40℃, the mote ratio of Zn^2＋/Mg^2＋=1：2, concentration is 6×10^-6-8×10^-6mol·L^-1, an the dosage is 0.03g, the ZnMgA1 - LDHs to methylene blue has good adsorption performance. Key words： LDHs; spectrophotometer; adsorption; methylene blue
