Abstract
Abstract:
Two polymer particles have been prepared by the reaction of N, N, N', N'-tetrakis(4-
aminophenyl)-1,4-benzenediamine, 4, 4-biphenyldialdehyde and isophthalaldehyde, and characterized
by SEM, FTIR and XRD. Based on methylene blue as the model pollutant, the adsorption properties
of two polymer particles have been observed by using different adsorbent dosages, adsorption times
and adsorption temperatures. Experimental data show that the removal rates of methylene blue
wastewater are 74 % for polymer A and 68 % for polymer B, and the removal rates are up to 84% for
polymer A and 74 % for polymer B after photo-catalytic treatment. All these suggest that the adsorption
performance of polymer A is more excellent than that of polymer B. In addition, the methylene
blue adsorption of the two Schiff base products conforms to the Freundlich adsorption isothermal
model.
