花生壳和核桃壳对活性艳蓝KN-R的吸附特性

The Characteristics of Reactive Brilliant Blue KN- R Adsorbed by Peanut Shells and Walnut Shells

以花生壳和核桃壳为原料,制备了两种吸附剂。研究了它们对活性艳蓝KN-R的吸附特性,并与活性炭进行对比。结果表明,这两种吸附剂在p H值为2时吸附效果最好,吸附率分别为84%和58.4%。这两种吸附剂适用于处理低浓度的KN-R废水,处理时间90 min为宜。

Two adsorbents are prepared by peanut shells and walnut shells. The characteristics of reactive brilliant blue KN- R adsorbed by them are investigated and compared with activated carbon. Results show that adsorption effects of two adsorbents are best when p H value is 2 and the adsorption rates are 84% and 58. 4% respectively. At the same time,they are suitable for the treatment of low concentration of KN- R wastewater and the processing time of 90 minutes is advisable.
