摘要
本文研究了竹炭的不同含量以及改性竹炭对水的吸附量，并利用分光光受法测试样品对刚果红溶液、亚甲基蓝溶液的吸时性能。结果表明，竹炭加入量BC为8．0wt％时，吸水倍率为436．44g／g；改性竹炭FeCl3的吸水倍率为463．42g／g。对母液浓度为50mg／L亚甲基蓝的吸附容量均为48mg/g左右。因此，经过改性后的竹炭对水的吸咐性能更好，这对制备得到新型多功能复合吸咐材料奠定基础。
In this paper, the different content of bamboo charcoal and the adsorption capacity of modified bamboo charcoal to water were studied, and the adsorption properties of the samples were tested by spectrophotometry. The results showed that the water absorption rate was 436.44g/g when BC was 8.0 wt%. The water absorption ratio of modified bamboo charcoal FeCl3 was 463.42g/g. The adsorption capacity of 50mg/L methylene blue was about 48mg/g. Therefore, the modified bamboo charcoal has better adsorption performance of water, which is the foundation for the preparation of new multifunctional composite adsorption materials.
