摘要
人工养殖海带经交联和酸处理,制得颗粒状吸附剂,研究该吸附剂与铅、镍离子的交换行为。结果表明:配比、、温度、时间等条件影响吸附性能。其吸附行为在一定的温度和浓度范围内较好地符合pH等温吸附线。
The artificially cultured kelp (Laminaria japonica) is dealt with hydrochloric acid and crosslinked with glutaraldehydev to produce the granular sorbent. The exchange and adsorption of Ni2+and Pb2+on kelp is examined. In terms of the results, the influence of pH and time on adsorption is also discussed. The results show that the adsorption rate increases with pH value and achieves more than 90 % within 20 min. Moreover, Freundlich isotherm is good appropriate type for this adsorption under given temperature and concentration.
