摘　　要：为了研究核桃壳对铁的吸附性能,用云南产普通核桃壳进行除铁的静态吸附试验研究,考察核桃壳对铁的去除效果。结果表明核桃壳对铁有一定的去除效果。得到核桃壳的最佳投加量为500g/L,最佳吸附时间为120min,最佳吸附含铁浓度为0.1g/L,去除率可达94.56%。对铁的吸附规律较好地符合Freundlich吸附等温式。In order to study the walnut shell effect of the iron adsorption use the ordinary walnut hulls in Yunnan to study the iron Static adsorption in water,and investigate the walnut shell effect of the iron removal.The results show that the walnut shell on a certain removal of iron in water.The best dosage of the walnut shells is 500 g /L,the best adsorption time is 120 mim,the best absorption of iron concentration is 0.1 g /L,the removal efficiency is 94.56%.The adsorption of iron is better meet the the Freundlich isotherm.
