摘要 为了解决过多向自然界排放含有重金属的废物,造成生态环境破坏问题,根据地聚物水泥具有很好的吸附性能及在处理含有铅废物方面特殊作用,本实验中添加天然沸石对粉煤灰基地聚物水泥改性,通过XRD证明有结晶的沸石相P型沸石结晶和方沸石出现,并用静态吸附试验证明改性后吸附能力增强,探讨了地聚物水泥水化产物粉体对铅的吸附性能及其主要影响因素。 In order to solve the problem of excessive release of heavy metals into the environment,because of geopolymers' excellent ability to adsorb ion to be used as an altermative technology for treatment and disposal of heavy metal waste,the fly ash based geopolymers solidification materials was modified by the natural zeolite. XRD showed that it had the zeolite P and the analicime-C, and it had ability to adsorb lead-ion beyond non-modified geopolymers. The ability of geoploymers of adsorbing lead affectsed by pH, concentration and temperature was discussed.
