摘    要:作者报道了利用PVA包埋固定化的叶绿素钠对铅离子的吸附特性.研究表明,纯PVA对金属铅的吸附率仅为4.5%.而在相同条件下,经PVA包埋固定的叶绿素钠盐对铅的吸附率可达84.5%.文中详细讨论了溶液pH值、温度、原液浓度、再生条件和重复使用次数对铅的吸附率的影响.

关 键 词:叶绿素钠  固定化    吸附  叶绿素  Pb^2+  吸附性能  钠盐  溶液pH值  铅离子

Abstract:The adsorption capability of immobilized chlorophyll sodium for lead ion is studied for the first time in this artiele. It is indicated that adsorption effieieney of pure PVA for lead ion is only about 4.5 %, but that of chlorophyll immobilized by PVA rcaehes to 84.5 96 under the same conditions. The effect faetors on lead adsorption efficiency are discussed in detail in this paper, such as pH, temperature, concentration of lead, regeneration conditions and reusing times.
Keywords:chlorophyll sodium  immobilization  lead ion  adsorption
