Sodium carbonate (Na2CO3) was employed to thermally modify the fly ash at elevated temperatures. The modified subjected characterization validate its enhanced adsorption capacity. Moreover, in contrast conventional methods such as static, stirring, and oscillation, an ultrasound-assisted approach adopted facilitate of Cu2+ by thermal (TFA). A comprehensive set single-factor experiments orthogonal were conducted investigate influence six common factors on adsorption. optimal conditions within experimental range determined follows: ultrasound time 40 minutes, temperature 40°C, power 100W, pH value 5, TFA dosage 0.50 g/L, initial concentration 50 mg/L. Under these optimized conditions, capacity reached 13.64 mg/g. This study investigated modification methods, mechanisms, relation adsorption, providing a valuable basis reference for application field
