A Synthesized Process of Acidic Tin-plating Waste Solution in Laboratory
In the electroplating process of acidic tin-plating in laboratory,temperature is required to control at 5 ℃ or so,but conditions of the laboratory is limited,the average temperature is above 5 ℃,which leads to Sn2+ in the bath hydrolyze,produce Sn(OH)2 impurities,and part of Sn2+ in the anode oxidize to produce metastannic acid.As time goes by,impurities increase gradually and eventually lead to the bath not be recycled.This paper mainly studied on impurities in the waste after electroplating were synthesized after a series of oxidation,filter and reduction,which makes recycled materials recycled to the greatest extent,non-recycling materials buried deep after high-temperature incineration.After the experiment,stannous oxide and distilled water in the waste get recycled,and the purity of stannous oxide gotten recycled is above 99.5%,which can be reused.
