The results show that the hydrogen bond is the main force between β-cyclodextrin and bilirubin. After the adsorption of bilirubin for 2 h, the adsorption capacity is over 90 %.展开更多

Polymer ofGMA with planned molecular weight and narrow molecular weight distribution was obtained. In caseof bulk polymerization with the same initiator and catalyst the molecular weight of the polymerobtained was 1.5～2. 1 times greater than that of the above one. By using 1-phenylethyl chloride(PECl)/CuCl/BPY as catalyst controlled ATRP of GMA has failed whether it was in bulk or insolution.展开更多
The study on separation of bilirubin by liquid membrane showed that ethyl acetate is an appropriate carrier for bilirubin, its clearance efficiency for bilirubin is 99 9% in 0.1 mol/L aqueous phosphate buffer and 83% ...The study on separation of bilirubin by liquid membrane showed that ethyl acetate is an appropriate carrier for bilirubin, its clearance efficiency for bilirubin is 99 9% in 0.1 mol/L aqueous phosphate buffer and 83% in simulated human serum albumin solution. In comparison with the adsorption of bilirubin by macroporous resins, liquid membrane possesses the merits of more rapid separation rate and higher clearance efficiency.展开更多
