First, a variety of instrumental analysis characterization methods such as BET, XRD, SEM are adopted to carry out the detailed component analysis for lead paste before and after desulfurization. Then the impacts of different carbonates (Na2CO3, NH4HCO3, (NH4)2CO3) on the desulfurization efficiency of waste lead paste are explored. Through orthogonal experiment and variance analysis to explore the impact of different desulfurization agent and different experimental conditions on desulfurization efifciency, we can conclude that sodium carbonate has a high desulfurization level. At the same time, using the orthogonal experiment analysis software, we can determine the influences of different factors on the desulfurization effects of desulfurizing agents. The results show that the desulfurization rates of lead paste by using sodium carbonate, ammonium bicarbonate and ammonium carbonate as desulfurizers respectively are 97.08 %、93.96 %、92.90 % at their respective optimum reaction conditions.
