In this paper, healthy fuactions and mechanismof bamboo-charcoal modified polyesters arc studied. Theresults show that there are five healthy functionsincorporated effectively in bamboo-charcoal modifiedpolyesters, such as good far-lnfrared radiation, good UVprotection, certain negative ion emission, certain anti-bacteria and good absorption functions. The metal elementsand carburets are mainly responsible for far-infrared,negative ion emission functions. UV prevention functionresults mainly from the carbon elements. The absorbabilityand bacteriostasis functions lie in the porous structures. 相似文献

本研究了竹炭对溶液中2,4-二硝基氯苯(CDNB)的吸附行为。研究确定竹炭对CDNB的吸附平衡时间、最佳吸附pH以及吸附温度、吸附剂用量等因素对吸附效果的影响。实验结果表明:CDNB初始浓度c0=0.05mg/mL,T=298K,pH=5.0,吸附时间t=12h时,竹炭对CDNB的吸附率E可达到97.6%;用乙醇作洗脱再生剂,洗脱率可达95.2%;且脱附的CDNB可用蒸馏重结晶法回收,回收率可达86.4%。因此,竹炭是废水中CDNB吸附处理的材料。 相似文献
