The removal of Mo(Ⅵ) from wastewater was studied by using jarosite after iron deposition in zinc leaching solution as adsorption material. The effects of the initial pH of simulated wastewater, the initial mass concentration of Mo(Ⅵ), the additon amount of jarosite and the adsorption time on the adsorption of Mo(Ⅵ) by jarosite were investigated, and the kinetic mechanism of the adsorption process was discussed. The results show that under the conditions of initial mass concentration of Mo(Ⅵ) of 40 mg/L, pH=3.0, additon amount of jarosite of 1.0 g/L and adsorption time of 240 min, the adsorption capacity of Mo(Ⅵ) can reach 13.21 mg/g. The adsorption process of Mo(Ⅵ) in wastewater by jarosite is more suitable to be described by quasi-second-order kinetic model, which belongs to chemical adsorption. The adsorption process of molybdenum by jarosite follows the Langmuir isothermal adsorption model and has higher fitting accuracy. The adsorption process belongs to monolayer molecular adsorption. This method has the advantages of simple process and low cost, and is expected to realize high-value recycling of waste residue.
