摘要
利用HNO3改性活性炭,研究了经HNO3改性后活性炭吸附处理白酒中重金属(Pb)。活性炭添加量为0.3%左右,搅拌8 h后,静置过滤,利用火焰原子吸收分光光度计检测。结果表明,利用经HNO3改性处理后的活性炭处理白酒,白酒中重金属(Pb)去除率达到96.7%。
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%.
