Preparation of Ultrafine Barium Sulfate Using Sodium Sulfate Content Wastewater

Abstract:

The wastewater from folic acid production contains a large amount of sodium sulfate. In this paper, this sodium sulfate wastewater was used to react with the industry black salt (barium sulfide) to prepare barium sulfate. By adjusting the feeding mode, reaction temperature, reactant concentration and stirring speed, the optimal experimental condition was determined. The barium sulfates particle size under this condition was 320 nm, with good whiteness but low energy consumption. The product not only turns the waste to useful product successfully, but also meets Chinese policy of energy-saving, emission reduction and sustainable development.
