研究醋糟在模拟废水中吸附Pb2＋的性能。考察温度、pH 值、吸附时间、吸附剂用量和初始Pb2＋浓度等对醋糟吸附Pb2＋的影响。结果：醋糟在较广泛pH 范围3～10，温度25～40℃时，对低浓度废水中的Pb2＋具有较高吸附率，醋糟对Pb2＋的吸附率达到91％以上。醋糟对Pb2＋的吸附为快速吸附，在初始Pb2＋浓度低于64．84 mg／L、醋糟用量33．33 g／L时吸附率达到94％以上。醋糟用量在7 g／L时，吸附率达到92％以上。Na＋，K＋对醋糟吸附Pb2＋的影响较小，Ca2＋，Mg2＋在浓度大于500 mg／L 时，会对醋糟吸附Pb2＋造成一定影响。结论：醋糟对固态发酵醋产品铅含量控制有一定影响；醋糟的再利用需防止重金属污染；醋糟可作为低浓度含铅废水的潜在吸附剂。

The adsorption property of vinegar residue on Pb2+ in simulated wastewater is studied for better application of vinegar residue.The effects of temperature,pH,adsorption time,initial Pb2+concentration,etc.,on the adsorption of Pb2+ are investigated.Results:The vinegar residue has a high adsorption rate on Pb2+ in a wide pH and temperature range.The adsorption rate of vinegar residue on Pb2+ is above 91% in pH 3~10 and at the temperature of 25~40 ℃.The adsorption of Pb2+ by vinegar residue is fast.The adsorption rate is higher than 94% when the initial Pb2+concentration is less than 64.84 mg/L and the amount of vinegar residue is 33.33 g/L.The adsorption rate is more than 92% when the amount of vinegar residue is 7 g/L.Na+ and K+ have little effect on the adsorption of Pb2+ by vinegar residue.Ca2+ and Mg2+ could significantly affect the adsorption of Pb2+ by vinegar residue when the concentration is more than 500 mg/L.Conclusion:The content of lead in solid-state fermented vinegar is influenced by vinegar residue.Heavy metal pollution should be prevented when vinegar residue is reused.Vinegar residue is a kind of safe natural product for Pb2+removal.
