Influence mechanism of pressure on the toluene desorption from active carbon under supercritical CO2

Preparation of magnetic activated carbon fibers@Fe 3 O 4 by electrostatic self-assembly method and adsorption properties for methylene blue

“…At the preparation temperature of 50°C, the adsorption rate increased to 82.69% and continued to decrease with increasing temperature. Xian-hang et al [23] found that the effect of temperature on the desorption effect was reflected in two aspects, the unfavourable factor is the density effect and the favourable one is the diffusion effect, which ultimately depends on the competition between the two. According to our previous research [17], most of the specific surface Ms (emu/g) 30 000 20 000 10 000 10 000 20 000 30 000 area and pore volume of CACF are provided by micropores (pore size <2 nm).…”
