Experimental Study on Preparation of Ferrous Oxalate with Titanium Dioxide Waste Water AITranslate
Abstract AITranslate
Titanium dioxide waste water is a kind of acidic waste water containing a lot of iron ions, which has important recovery value.Using titanium dioxide waste water as raw material, ferrous oxalate was prepared by adding sodium oxalate.The effects of sodium oxalate dosage, reaction temperature, stirring strength and reaction time on the precipitation rate of iron were analyzed.The phase and microstructure of the precipitated products were analyzed by XRD and SEM-EDS.The results show that the precipitation rate of iron is more than 82% under the optimized conditions of titanium dioxide waste water volume of 50 mL,temperature of 20 ℃,sodium oxalate dosage of 12 g, stirring strength of 300 r/min and reaction time of 30 min, and the precipitate is the granular crystal of ferrous oxalate dihydrate with a purity of more than 98%.This study provides a method for efficient recovery of iron resources in acidic solution system.
