研究活性炭吸附维生素B_3和维生素C以及在模拟体内环境中的释放过程.探讨了活性炭孔结构对吸附维生素B_3和维生素C的影响,并对活性炭缓释维生素B_3过程进行了数学模拟,初步探讨了吸附和释放机制.实验所用活性炭对维生素B_3有较强吸附能力,吸附量达到了94.9 mg/g,对维生素C的吸附量仅38.5 mg/g.采用活性炭对维生素B3有良好的缓释性能,其整个释放过程符合药物体外释放一级动力学模型为Q=38.25-36.90e~(-0.049 24t).所用活性炭适于作为缓释维生素B3的载体,而由于维生素C的不稳定性,不适宜使用活性炭缓释.

Adsorption of vitamin B_3 and vitamin C by activated carbons and their controlled release were investigated in this paper.The effect of pore structure of the activated carbon on the adsorption of vitamin B_3 and vitamin C was studied.The process of vitamin B_3 release was simulated and the mechanism for adsorption and release was also discussed.The activated carbon possessed high adsorptive capacity for vitamin B_3,with the amount of 94.9 mg/g,but the value for vitamin C was only 38.5 mg/g.The release process was marched with first-order kinetic model Q=38.25-36.90e~(-0.049 24t).The activated carbon might be used as the carrier for vitamin B_3 release, but not suitable for vitamin C due to its instability.
