The concentration of endotoxin in endotoxemia patients′ blood increases quickly and leads to severe sepsis, leading to severe hypertension, cardiovascular continues to have a high failure and death, which is a major cause of death in patients and continues to have a high mortality despite appropriate surgery, potent antibiotic and intensive supportive therapy was conducted. Removal of endotoxin duly and effectually from patients′ blood is very important in clinic. Hemoperfusion can clear toxins from patient′s blood by adsorbent, not only small molecular toxins but also large ones in time. In this paper, the hemoperfusion adsorbent for removing endotoxin was prepared. The physical and chemical parameter of the adsorbent is investigated and the surface structure of adsorbent was investigated through ESEM. The influence of weights of adsorbents and adsorbing time on adsorption ability was also studied. The results showed that the adsorbent with lysine as the ligand had good affinity to endotoxin and the best adsorption capacity of it was 253.1 EU/g when the initial concentration is 10 EU/mL. The blood compatibility of the adsorbent was also studied and the results indicated that the adsorbent has clinic application foreground.展开更多
