The results show that: with the increasing concentration of collagen, the adsorption amount and initial adsorption rate on spin-coated PLA surface increases correspondingly.
实验结果表明：随着胶原浓度的增加，胶原在聚乳酸表面的吸附量和吸附初速率都相应增加。
The adsorption rate and equilibrium adsorption capacity increased slightly with the initial concentration.
吸附速率及平衡吸附量随初始浓度的升高而略有变大。
The lower the initial SDBS concentration, the faster the adsorption rate and the shorter the time reaching adsorption equilibrium necessary were.
溶液的初始浓度对吸附速率产生明显影响，浓度越低吸附速率越快，达到吸附平衡所需的时间越短。
