- Abstract:
- Polyethylenimine/Salix(PEI-SP)was prepared by epichlorohydrin crosslinking for application in the adsorption of acid chrome blue K(ACBK)from aqueous solution.The adsorption kinetic models and the adsorption isotherm models were used to fit the obtained experimental data, respectively.The results showed that the kinetic process was best predicted by the Elovich model, which indicated the adsorption process was an inhomogeneous chemisorption process and the adsorption rate was controlled by film diffusion.The equilibrium isotherm was best fitted with the Koble-Corrigan model, which indicated that the adsorption of ACBK by PEI-SP was mainly monolayer adsorption, while accompanied by multi-molecular layer adsorption.The maximum adsorption capacity of PEI-SP calculated by Langmuir model for ACBK was 0.428 mmol/g at 298 K.As could be seen from the influence of pH value on the adsorption capacity, the adsorption capacity of PEI-SP on ACBK gradually decreased with the increase of pH value.When pH<6.78, ACBK was mainly adsorbed on the surface of PEI-SP by electrostatic attraction.Combining the results of the infrared analysis and the effects of pH values on the adsorption capacity, the adsorption mechanism of ACBK on PEI-SP were electrostatic interaction, hydrogen bonding, and π—π stacking interactions.The results of desorption and regeneration experiments showed that the adsorbent could retain its adsorption capacity after three cycles operations, showing excellent regenerability.It was implied that PEI-SP has a promising application in the removal of anionic dyes from wastewater.
