Research on the Recovery and Utilization of Tin Sulfate Waste Liquid
The recovery and utilization process of stannous sulfate waste liquid was studied.Explored the effects of factors such as vacuum de-gree,heating time,type of stabilizer,and amount of stabilizer added on the product.When the volume ratio of the lower waste liquid to water is 1∶2(500 mL of lower waste liquid,diluted to 1500 mL with water),0.8 g of stabilizer2 is added,the vacuum degree is0.08MPa,the tempera-ture is(55±2)℃,and the heating time is(90±5)min,the turbidity of the produced stannous sulfate is low,and the product quality meets relevant standards,achieving efficient and intensive resource utilization.
