摘要
以微米级交联微球HEMA(甲基丙烯酸β-羟乙酯)/NVP(N-乙烯基吡咯烷酮)为固体吸附剂,对大黄素分子进行了吸附研究。静态吸附实验结果表明,凭借常规氢键和π型氢键的作用力,吸附剂对大黄素分子具有较强的吸附能力,等温吸附满足Langmuir吸附模型;溶剂的极性以及温度都会对吸附作用产生影响。
The adsorption characters of emodin were conducted by ceosslinked HEMA （hydroxyethyl methacry-late） /NVP （ N - vinylpyrrolidone） microspheres as solid adsorbent. Static adsorption experiment results indicatethat by the conventional hydrogen bond with multiple sites and n type hydrogen bond between the crosslinked HE-MA/NVP microspheres and emodin, the crosslinked microspheres can produce strong adsorption capacity for emod-in. The isothermal adsorption was accorded with Langrnuir equation; the polarity and temperature of solvent mightexert great effect on adsorption capacity of HEMA/NVP.
