| 摘 要： | 根据竹炭的制备原理，利用微波辐照技术代替传统的加热技术在N2、CO2。氛围中对竹炭进行改性，以期提高竹炭的吸附性能。通过比表面积测定及亚甲基蓝吸附值测定，探讨了微波功率、辐照时间及样品粒径3种因素对改性后竹炭吸附能力的影响。结果表明，微波加热有效地提高了竹炭的吸附能力，微波功率和辐照时间是决定改性竹炭吸附性能的关键因素；并通过改性前后竹炭对常见重金属离子和卜的吸附性对比，发现改性后的竹炭对常见重金属离子和F^-的吸附性能大有改观，该法有望成为提高竹炭吸附性能的有效手段。

| Abstract: | According to the principle of the bamboo-carbon preparation,thermal treatment of the bamboo-carbon in atmosphere of N2 and CO2 gas has been carried out using a microwave device instead of a conventional furnace in order to increase the adsorption capacity on the bamboo-carbon.By fire of the mensuration of the specific surface area and the adsorption value of methylene blue,the influence adsorption effect of the power of microwave,radiation time and particles diameter of samples after reshaping is studied.It is shown that the adsorption capacity on the bamboo-carbon modified by microwave is increased obviously,and power of microwave and radiation time are the key factors to decide adsorption ability on the bamboo-carbon modified.By the contrast of adsorption capacity of the bamboo-carbon before and after being modified by microwave to heavy metal ions and F-,it is shown that the adsorption capacity on the bamboo-carbon modified is increased clearly.The technology can become an effectual means to increase the adsorption capacity of the bamboo-charcoal. |
