- W2365605416 abstract "Poly(allylamine)-grafted silica gel(PAA/SiO2) with amino group content of 1.81 mmol g 1 was synthesized by using-chloropropyltrimethoxysilane as coupling reagent and poly(allylamine) as surface-modifying reagent.The thermodynamics,kinetics and selectivity of Cu2+ adsorption by prepared PAA/SiO2 were studied.The experimental results show that the pH value of Cu2+ solution affects the adsorption capacity of the PAA/SiO2 significantly,and its adsorption capacity for Cu2+ at pH=4.0 is 0.397 mmol g 1.The measured adsorption equilibrium data for Cu2+ could fit the Langmuir model well.The calculated results of Cu2+ adsorption thermodynamic parameters of PAA/SiO2show that the Cu2+ adsorption is endothermic spontaneous process,and increasing temperature is conductive to the Cu2+ adsorption.It was found that the adsorption kinetic data could be fitted by the pseudo-second-order kinetic equation,and the fitted kinetic constants are related with the initial solution concentration.The results of its selectivity study show that the PAA/SiO2 possesses recognizing ability for Cu2+ and its selectivity coefficient is about 2~4 in relation to Zn2+.Besides,the synthesized PAA/SiO2 is easy to be regenerated and can still maintain up to 91.1% of its initial Cu2+ adsorption capacity after five adsorption-regeneration cycles." @default.
