摘　　要：试验旨在研究超细电气石粉对水体中亚甲基蓝的吸附性能,探讨了吸附时间、电气石用量、溶液初始浓度以及吸附温度对电气石吸附溶液中亚甲基蓝效果的影响,结果表明:(1)电气石对溶液中的亚甲基蓝有良好的吸附性能。室温条件下,当电气石用量为2.5 g/L、吸附时间为40 min、自然pH值、溶液浓度为50 mg/L时,电气石对溶液中亚甲基蓝的吸附率为95.81%。(2)电气石对溶液中亚甲基蓝的吸附符合Langmuir吸附等温式,在温度为20、30、40和50℃条件下,电气石对亚甲基蓝的最大吸附容量分别为64.52、68.89、68.07和65.41mg/g。The examination was conducted to study the adsorption properties of tourmaline on methylene blue in the water and to discuss the effects of the adsorption time,tourmaline,initial concentration of solution and adsorption of acetylene adsorption temperature on methylene blue aqueous solution. The result of the test indicates as follows:( 1) Tourmaline on the adsorption of methylene blue in aqueous solution is provided with good performance. At room temperature,the adsorption time of tourmaline is 40 min when the dose is 2. 5 g/L,and when the nature and solution pH value concentrations attains 50 mg/L,the adsorption rate of tourmaline for methylene blue in the solution is95. 81%.( 2) Tourmaline on adsorption of methylene blue solution is in line with the Langmuir isothermal adsorption equation,under the conditions within the range of 20,30,40 and 50℃ temperature,maximum adsorption capacity of methylene blue tourmaline is 64. 52,68. 07 and 65. 41mg/g respectively.
