摘要
本文采用浸渍法将Cu^(2+)负载于凹凸棒土,制备一种以凹凸棒土为基质的新型吸附材料,并研究了Cu^(2+)改性凹凸棒土的制备条件、凹土结构,相关性能。结果表明:浸泡时间7.5h、浸泡温度60℃、反应浓度为0.15mol/L等条件对对改性产品的性能有较大的影响;负载Cu^(2+)的凹凸棒土既保持了多孔性材料的广谱吸附性,也增强了其吸附特定有害气体能力特别是对NH3的吸附速率和容量均匀较大的提升,同时还具有明显的吸附显色功能和长效防霉效果。
This paper introduces the method,loading Cu^(2+)on attapulgite by dipping,to preparing a new attapulgite-based adsorbing material,and researches the preparing condition,structure,relevant properties of the attapulgite modified by Cu^(2+).The results show that the dipping conditions including the time of 7.5 h,temperature of 60℃,reaction concentration of 0.15 mol/L,etc.,have great influence on the properties of modified products.Cu^(2+)-loaded attapulgite not only maintains the broad-spectrum adsorptivity of the porous material,but also enhances its ability to adsorb specific harmful gases,especially the large rise of speed and volume in adsorbing NH3.While adsorbing,it can show the color of NH3 and long-term anti-mold.
