【摘要】 线型酚醛树脂中添加不同的造孔剂 ,制备出 3种孔径分布的酚醛树脂基球形活性炭。考察了它们对血液中有代表性的生理中小分子VB12 和肌酐的吸附行为。结果表明 ,这 3种球形活性炭对肌酐均有良好的吸附性能 ,而对VB12 的吸附性能相差较大 ;比表面积大的试样对肌酐的吸附量大 ,中孔孔容大的试样对VB12 的吸附量大更多还原

【Abstract】 Three kinds of phenolic resin based spherical activated carbon (PHSAC) with different pore size distribution were prepared by adding pore formers into novolac type phenolic resin.Their adsorption abilities to creatinine and VB 12 were also studied.The results showed that these three PHSACs had good adsorption ability to creatinine,but for VB 12 adsorption these PHSACs showed quite different ability.PHSACs with higher surface area has larger adsorption capacity to creatinine.PHSAC with bigger mesopore volume has larger adsorption capacity to VB 12 .更多还原
