In this study, active carbon was modified using HNO3, then the modified active carbon was used in the treatment of heavy metals (Pb) in Baijiu(liquor) (the use level was about 0.3%, after 8 h stirring, static filtration, and the absorption effects measured by flame atomic ab-sorption spectrophotometer). The experimental results showed that, the use of modified activate carbon in the treatment of Baijiu(liquor) could achieve the removal rate of Pb up to 96.7%.
