The influences of the factors, such as chitosan(CS), polyethylene glycol(PEG), beta-cyclodxtrin(B-CD),vinyltriethoxysilane(JH-V151), etc. on the treatment capabilities of the prepared CS/PEG/B-CD composite membrane for copper-containing wastewater have been investigated by means of using single-factor tests combined with Box-Behnken response surface method, and taking adsorption capacity as the index. The optimal preparation conditions of CS/PEG/β-CD composite membranes are determined as follows:m(PEG)∶m(CS...
