The Reaction Kinetics And Reaction Thermodynamic Study On The Ion Exchange Behaviour Of 2NH₄～+(Z)=Cu～(2+)(S) In Baimiaozi Clinoptilolite

NH+4-activated clionptilolites were used to improve copper ion adsorption capacity of material in this paper.We can inclcusionfrom the characterized by means of chemical analysis,XRD,FT-IR,TG-DTA,specific surface and pore structure spectroscopy.The results indicates that their crystal structures and thermostability have no obvious change ,but surface and pore have great improve.Under the different temperature and density ,we do some experiment of kinetics and thermodynamic ,and we have some work to fit Langmuir equation Frendlich equation D.R. equation isotherm Study on kinetics and thermodynamatic of vacuole diffuse constant R , hilum diffuse constant and resort time,balance exchange capacity ,exchange efficiency ,ion revise choice quotient and △Gmθ △RHmθ △RSmθ.We find,the first phases is vacuole diffuse residual time is hilum diffuse . Temperature and density have great influence adsorption velocity and resort time,the same to Q_∞ η K_cand more the affinity have some change.
