Thermodynamic analysis of aniline adsorption on polyethylene terephthalate with polyethylene glycol
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Thermodynamic adsorption parameters of aniline monomer on polyethylene terephthalate (PET) with polyethylene glycol (PEG) were investigated. The standard affinity (-Δμ0 ) decreased when the number of methylene in PEG increased testing from PEG200 to PEG800. According to the changes of the enthalpy (ΔH0
