Using a novel adsorbent macrocyclic compound cucurbit[8]uril for Pb2+ removal from aqueous solution.

Abstract

In this study, cucurbit[8]uril (CB[8]) was utilized as a kind of new adsorbent to remove Pb2+ ions from aqueous solution. With the solution pH increased from 2 to 6, the removal efficiency of adsorption increased from 55.6% to 74.5%correspondingly. The uptake of Pb2+ increased rapidly in the initial 30min, and then the adsorption rate became slower. The… (More)
