From 10 to 40 minutes, the adsorption amount of BPA increased slowly with final equilibrium at 40 minutes and adsorption capacity of 487.69 ± 8.37 mg g−1.
In the first 10 minutes, the adsorption amount of BPA increased significantly and the adsorption capacity of 407.14 ± 6.08 mg g−1 was reached.
Generally speaking, the higher the electronegativity, the larger the adsorption amount.
Under the optimum condition, the adsorption amount of Cu2+ was 35.2 mg/g adsorbent.
In general, the adsorption amount appeared to decrease with the increase in ionic strength.
H2 adsorption amount and pumping speed were significantly larger than CuO and CuO & 5A getter systems.
Moreover, adsorption amount, zeta-potential, DFT calculation, XPS, and FTIR were performed to study the mechanisms.
The adsorption amount of state 1 presented unimodal shape and adsorption amount of state 2 presented sigmoid with the growth of П.
As the degree of swelling decreased, the adsorption amount increased to eventually achieve a constant value.
Further experiments were designed to demonstrate that the adsorption amount is depended on both textural and surface properties.
It was found that although original MIL 53 had the best adsorption amount, its separation efficiency is not very high.
