摘要
研究了不同活化条件对沥青基球状活性炭表面物理结构的影响,并初步探索了其作为医学吸附材料对维生素B12及肌酸酐的吸附性能。结果表明:改变活化条件,可在一定范围内控制沥青基球状活性炭的孔径;在实验条件下,沥青基球状活性炭对维生素B12及肌酸酐的吸附率分别达到80%及96%。
The activation condition was changed to get a series of pitch-based spherical activated carbon(PSAC),then the structure and adsorption capacity of PSAC was measured. It is found that alteration of the activation condition can control the pore distribution of PSAC in specified ranges, and its adsorption ability to vitamin B12 and creatinine can reach 80 % and 96 % respectively.
