离子交换法回收废水中钼金属的研究

Recovery of Molybdenum from Wastewater by Ion Exchange Process

含钼废水中钼金属浓度一般在1 g/L以上,将这些废水排放,不仅造成环境的污染,而且会造成资源的浪费。本文通过研究不同废水中钼的价态形成的机理,选取D-314树脂、ZS-1螯合树脂和HYA-18树脂对不同含钼废水进行动态吸附模拟实验,研究了影响吸附和解吸过程中的因素。

Generally,the concentration of molybdenum metal in molybdenum-containing wastewater is more than 1 g/L.The discharge of these wastewater not only causes environmental pollution,but also causes waste of resources.If an effective method can be used to recover molybdenum metal from wastewater,it will not only produce objective economic benefits,but also have the significant environmental benefits.In this paper,by studying the formation mechanism of molybdenum valence state in different wastewater,D-314,ZS-1 resin and HYA-18 resin were selected to carry out dynamic adsorption simulation experiment on different molybdenum-containing wastewater and the factors affecting the process of adsorption and desorption were studied.
