摘要
大豆豆皮作为生物吸附剂,通过振荡方法吸附Pb2+浓度为10 mg/L的模拟重金属废水。研究结果表明,当吸附时间为60 min,温度为30℃,pH=2～3,豆皮投加量为2 g/L时,Pb2+的去除率达到99.48%。此外,还对豆皮吸附Pb2+后的解析性能作了考察,其解析率达到94%以上,而且可反复使用,豆皮是安全的天然产物,可用于去除废水中的重金属离子,也可用于去除饮用水中的重金属离子。
Reported the feasibility of adsorption of heavy metals from simulated heavy metal wastewater with 10 mg/L of Pb2＋ by using the soybean hulls.Results showed that removal rate of Pb2＋ was 99.48 % at 30 ℃,pH=2-3,with soybean hulls of 2 g/L for 60 minutes.Desorption rate of Pb2＋ was 94 %,which made soybean hulls could be used repeatedly.Soybean hulls were safe and environmentally-friendly natural products,and could be used as heavy metals adsorbents of waste water or drinking water.
