摘 要: | 采用还原载银法对改性竹炭进行载银试验,得到了不同载银量的载银竹炭。利用扫描电镜对其结构进行分析的结果表明,银主要分布在竹炭的外表面和大孔中。同时,对比了竹炭在载银前后的吸附能力,包括碘吸附值、苯酚吸附值、灭菌效果以及载银量对它们的影响,结果表明,该载银竹炭可基本保持其原有的吸附能力。而且具有一定的灭菌效果。

Abstract: | Bamboo -charcoal supporting silver were prepared by reductive method with modification bamboo - charcoal, obtained the bamboo - charcoal of different silver content. The structure of bamboo -charcoal supporting silver was analyzed by SEM, the distribution of Ag was mainly on the outside surface and in macropore of bamboo - charcoal. The adsorption capacities of bamboo - charcoal were compared before and after silver - loaded, parameters studied include adsorption value of iodine, adsorption value of phenol and antibacterial effect, and influence of silver - loaded content on its. The results showed that the bamboo - charcoal supporting silver retain basically intrinsic adsorption capacities, and possessed antibacterial capacity. |
