摘要
研究了竹炭吸附前,利用微波进行预处理的处理方法与效果.结果表明:微波处理后竹炭的比表面积与吸附能力有显著的提高,不同的竹炭用微波或NaOH加微波处理后,亚甲基蓝吸附值提高了34%～92%.该法用于吸附Pb2+后的竹炭的洗脱,竹炭的吸附能力恢复到原来的90%以上.该法有望成为竹炭活化的有效手段.
Bamboo-charcoal was pretreated with microwave or microwave with chemical reagent prior to its application. The methods and effects of pretreatment were studied. Results showed that specific surface area and adsorption capacity were elevated remarkably after pretreatment with the above mentioned methods, and the methylene blue adsorption values of bamboo-charcoal were increased over a range of 34 % - 92 %. The methods were used in regeneration of bamboo-charcoal after adsorption of Pb^2＋, and the percentages of regeneration was up to 96 %. The technology could be an effective means for activation of bamboo-charcoal.
