利用某铅锌冶炼厂冶炼烟气硫酸为原料，经分析化验，原料酸中杂质含量较高，直接蒸馏对试剂硫酸的质量影响较大。因此，在蒸馏前需对原料酸进行净化处理，对原料酸的净化工艺进行了试验研究，采用经过净化的原料酸制取的试剂硫酸产品指标达到国家标准GB/T625-2007化学纯指标要求。

s:By using smelting-flue-gas sulfuric acid from a lead-zinc smelter as raw material to prepare reagent sulfuric acid through the process of direct distillation , it has heavy impact on quality of the reagent acid due to that lab test shows high content of impurities in the raw material acid .Therefore, raw material acid should be purified before distillatio , and experi-mental test is carried out to study raw material acid purifying process .Reagent sulfuric acid prepared from purified raw ma-terial acid meet the specifications for Chemically Pure under the National Standard GB /T625-2007.
