The adsorption isotherm data of MTCFs@SIP@CBMA and MTCFs@NIP@CBMA to BSA
were further evaluated using Langmuir and Freundlich isotherm models.
The fitted linear curve is shown in Figure S2, and relevant parameters
are listed in Table 3. By
comparing R2, it can be seen that the Langmuir model
could better fit the adsorption isotherm data of MTCFs@SIP@CBMA and
MTCFs@NIP@CBMA. This illustrated
that the adsorption process was monolayer adsorption. The theoretical
maximum adsorption capacities of MTCFs@SIP@CBMA and MTCFs@NIP@CBMA
calculated by Langmuir model were 421.69 mg/g and 69.37 mg/g. These were
basically consistent with the experimental data.
