A high-speed dispersion homogenization-assisted alkali fusion-hydrothermal method was successfully developed for the preparation of NaA zeolite molecular sieve with excellent adsorption performance ammonia nitrogen using solid waste fly ash. The sieve, prepared at a calcination temperature 700 °C and crystallization 80 °C, identified as through XRD SEM tests, exhibiting uniform ordered cubic crystal structure. result BET analysis indicates that has specific surface area 288.219 m2/g plentiful pore And effect pH, time, initial concentration on capacity also investigated. fitting experimental data kinetics isotherm models kinetic solution by follows second-order model more closely. Langmuir shows better correlation than Freundlich model, suggesting is mainly based surface-uniform monolayer physical process. Under conditions pH = 7 an 100 mg/L, within 60 min can reach 27.5 mg/g, showing performance. This study establishes vital research foundation utilization ash treatment wastewater, great ecological social benefits.
