Popis:	This study was included (Snail shell modification) snail shell melamine formaldehyde polymer (SSMFP). It is an effective adsorbent to remove Azure A dye from aqueous solution. The effects of pH, contact time, ionic strength, temperature and amount of adsorbents were evaluated. The highest adsorption efficiency was recorded at 93.90% with 5 mg/L dye according to the Beer Lambert (Dye Calibration Curve), 0.0050 g of adsorbent 10 minutes contact time and 298 K. Elimination data using Temkin, Langmuir and Freundlich models were analyzed at different temperatures ranging from 298 to 338 K, and the adsorption thermodynamic parameters were studied. Where ΔG values indicate an automatic process, ΔH indicates the exothermic property of the adsorption process and ΔS proves an increase. The adsorption surface was also studied and diagnosed by FT-IR, X-RD, AFM, and SEM technologies
