Green valorization of municipal solid waste incineration fly ash into NaP1 zeolite via ultrasonic pretreatment: Low-carbon synthesis and robust oxytetracycline removal.

Ultrasonic pretreatment enables rapid, low-carbon synthesis of NaP1 zeolite from municipal solid waste incineration fly ash, reducing synthesis time by 50%.

• Why it matters: Transforming hazardous waste into valuable materials addresses environmental risks and promotes sustainable waste management, yet current methods are energy-intensive and costly.
• What they did: The study employed ultrasonic cavitation to accelerate amorphous phase dissolution, followed by microwave hydrothermal synthesis, producing IFA-NaP1 with significantly lower environmental impact and cost.
• The result: The resulting zeolite effectively adsorbs oxytetracycline at relevant concentrations, maintaining over 85% removal efficiency in complex wastewater, supporting its use in environmental remediation.
