氢氧化镁粉体制备及保护渔业水体方面应用

Manufacture of Super Fine Magnesium Hydroxide and its Application in Fishery Protection

[目的]研究氢氧化镁粉体制备对保护渔业水体方面的应用。[方法]研究了反应条件对氢氧化镁粉体分散性的影响,使用IR、XRD、SEM对产物进行表征,制得的氢氧化镁粉体用作重金属离子脱除,利用分光光度法考察了工艺条件对脱除效果的影响,获取最佳工艺条件,并在此基础上处理实际废水。[结果]经过处理的重金属废水达到排放指标,对渔业水体危害基本消除。[结论]该试验为保护渔业免受重金属污染提供了一定的理论基础。

[Objective] The manufacture of super fine magnesium hydroxide and its application in fishery protection were researched.[Method] The effect of reaction condition on the size and morphology of the final product was experimented.The super fine powder of magnesium hydroxide was prepared and characterized by lXRD,FT-IR and SEM for the removal of heavy metal.The treatment effect of it was tested with spectroscopy for the optimal technological condition.The technique was applied in the treatment of wastewater.[Conclusion] The indicators of the heavy metal in wastewater treated was met the standard,which did not damage the water body for fishery.
