Nanocomposite A has a surface area of 96 whilst nanocomposite B has a surface area of 54, yet nanocomposite B has a greater contaminant removal efficiency. Why ?
Also, I suspect that even though nanocomposite A has a larger surface area, there are fewer active sites present, how is this possible ?
Furthermore, is it possible that temperature has an effect ?
or is it possible that the size of the contaminant plays a role?
Riona Indhur Pore size is important for sorption absorption. The larger the specific surface area, the smaller the pore size. If the sorbate has pores comparable in size to the pores of the sorbent, it will not be able to be fully sorbed.
Hello: Yes, contaminant size is crucial for adsorption and transformation, as reported in the literature. Additionally, consider factors like the nanocomposite's particle size, active site distribution, and medium viscosity. Have you conducted the adsorption experiment under kinetic conditions? Does the process involve solely adsorption or also transformation. cheers!
