High Adsorption Capacity

The Ce-doped UiO-67 nanocrystals were successfully synthesized via a one-step hydrothermal method. Ce doping increases the negative charge on the surface of the material, thus the adsorbent exhibits high adsorption capacity to cationic dyes.

Abstract It remains a formidable challenge to construct high-performance haemoperfusion adsorbents with fast adsorption kinetic and high adsorption capacity for efficiently removing bilirubin from human blood. In this work, we report a facile yet efficient strategy to manufacture lysine-modified macroporous cellulose/carbon nanotube microspheres (LMCMs) by surfactant micelles swelling strategy followed by modification with lysine. The macroporous structure not only provides wide channels for fast mass transfer, but also shortens the diffusion path into meso/micropores, increasing the accessibility of mesopores and micropores. The experimental results reveal that LMCMs can remove bilirubin with fast adsorption kinetic (> 90% of its equilibrium uptake within 2h) and high adsorption capacity of 338.14 mg/g. More importantly, the adsorbent can remove about 79% of bilirubin in rabbit serum, and the bilirubin concentration decreases from 213.36 mg/L to small than 45.78 mg/L within 2h, indicating a very appealing application prospect.

High Adsorption Capacity

Steamed Hoof Powder (SHP), size < 53μ, was observed to have high adsorption capacity for Hg(II) with >95% removal from a solution containing 100 mg/L of Hg(II) with only 0.1% (W/V) concentration of SHP. The SHP has good settling properties and gives clear and odour free effluent. Studies indicate that pH values between 2 and 10 have no effect on the adsorption of Hg(II) on SHP. Light metal ions like Na+, K+, Ca2+ and Mg2+ up to concentrations of 500 mg/L and heavy metals like Cu2+, Zn2+, Cd2+, Co2+, Pb2+, Ni2+, Mn2+, Cr3+, Cr6+, Fe2+ and Fe3+ up to concentrations of 100 mg/L do not interfere with the adsorption process. Anions like sulphate, acetate and phosphate up to concentrations of 200 mg/L do not interfere. Chloride interferes in the adsorption process when Hg(II) concentration is above 9.7 mg/L. The adsorption equilibrium was established within two hours. Studies indicate that adsorption occurs on the surface sites of the adsorbent.
