The production, qualitative and adsorbent study of β-cyclodextrin molecular engram

摘要

In the paper, the molecular engram polymer is produced by dithizone which is functional monomer, β-cyclodextrin which is pore-forming material and chloroepoxy propane which is crosslinking agent. Atomic absorption method is used to study its adsorption for lead. Thermodynamic model of adsorption and dynamic reaction order are discussed. The results show that adsorption is endoergic process and accords with Freundlich isothermal adsorption equation. Adsorption system conforms with pseudo-second order dynamic model, the static saturation adsorption amount is 45.55mg/g.
