Abstract
- Abstract: A novel hypercrosslinked polymeric adsorbent of LM-6 was prepared by post-crosslinking reaction with 2-naphthol. Bromoethane was used as crosslinking reagent to substitute poisonous organic compound of chloromethyl methylether. Selective adsorption on LM-6 in mixture solution which consisting of 2-naphthol and naphthalene shows that the adsorption of 2-naphthol and naphthalene in aqueous solution are mainly pushed by physical interaction. The adsorption of 2-naphthol is also partly pushed by chemical interaction. The adsorptive enthalpy illuminates that there exists hydrogen-bonding between 2-naphthol and LM-6. Owning to hydrogen-bonding, the adsorption capacity of 2-naphthol on LM-6 is markedly higher than that of naphthalene. In aqueous solution, the adsorption process contains two steps: desorption of water first and then adsorption of solute. Dynamic analysis shows that adsorption capacity of 2-naphthol is higher than that of naphthalene. The adsorption rate is mainly affected by the diffusion of liquid membrane, the diffusion inside particulate or coordinated effect. [Copyright &y& Elsevier]
