Abstract：The melamine molecule contained three free amino groups and three aromatic nitrogen atoms, so it had great adsorption potential to heavy metal ions. In order to investigate the adsorption property of this adsorbent to mercury ion, the adsorption capacity and adsorption rate of melamine to mercury ion were measured under different conditions including adsorption time, adsorption temperature, pH of solution and concentration of mercury ion. The results showed that melamine had good adsorption property to mercury ions. At 30 ℃ and pH 5.0, when 50 mg of melamine was used to absorb mercury ion in 25 mL of 5.430 mg/L mercury chloride solution for 6 h, the measured adsorption capacity was 606 mg/g and the adsorption rate was 38.9 %. The adsorption isotherm belonged to Freundlich mode. This adsorbent had good comprehensive adsorption property and price advantage, so it had wide application prospect in separation and enrichment of mercury ion and the treatment of wastewater containing mercury
