摘要：

A hyper-cross-linked polymeric adsorbent with "CH2phenolCH2" as the cross-linked bridge (denoted GQ-05), and another hyper-cross-linked polymeric adsorbent with "CH2p-cresolCH2" as the cross-linked bridge (denoted GQ-03) were synthesized to reveal the effect of the steric hindrance of micropores in the hyper-cross-linked polymeric adsorbent on adsorption capacity and adsorption rate of p-nitroaniline (PNA) from aqueous solution. The results of adsorption kinetics indicated the order of the adsorption rate GQ-05>GQ-03. The pseudo-first-order rate equation could describe the entire adsorption...
