Experimental Study on Preparation of Jarosite from Titanium White Waste Water AITranslate
Abstract AITranslate
Jarosite was prepared from titanium white waste water by adding potassium chlorate and potassi- um hydroxide. The effects of reaction temperature,solution pH and reaction time on Fe precipitation rate were investigated. And microstructure and phase composition of the precipitated product were also ana- lyzed. The results show that the precipitation rate of Fe from titanium white waste water is more than 99% under the conditions of temperature of 95 ℃, solution pH of 2.0 and reaction time of 40 min. The precipita- ted product is the acicular crystal of jarosite. In addition to the significant decrease of SO4^2-and Fe2＋ concentrations in the filtrate,the contents of the rare metal ions such as Ti,V and Sc are almost unchanged, which is beneficial for the separation and purification of rare metals in the next process step.
