摘要

Abstract

High concentrations of copper ions (Cu(II)) in water will pose health risks to humans and the ecological environment. Therefore

this study aims to utilize ultrasonic-cured modified municipal solid waste incineration (MSWI) fly ash for Cu(II) adsorption to achieve the purpose of “treating waste by waste.” The effects of pH

adsorption time

initial concentration

and temperature on the modified MSWI fly ash's adsorption efficiency were systematically studied in this article. The adsorption performance of the modified MSWI fly ash can be enhanced by the ultrasonic modification. At pH = 2

3 and 4

the adsorption capacity of the modified MSWI fly ash for Cu(II) increased by 2.7

1.9 and 1.2 times

respectively. Furthermore

it was suggested that the adsorption process of the modified MSWI fly ash can be better simulated by the pseudo-second-order kinetic model

with a maximum adsorption capacity calculated by the Langmuir model of 24.196 mg·g

-1

. Additionally

the adsorption process is spontaneous

endothermic

and chemisorption-dominated from the thermodynamic studies (∆

and ∆

∆

0). Finally

the enhanced adsorption performance of the modified MSWI fly ash for Cu(II) may be attributed to electrostatic interaction and chelation effects.
