In this study, squid melanin was used as adsorbent to remove of Pb^2＋ and Cr^6＋ from aqueous solutions, the adsorption factors including squid melanin content, adsorption time, adsorption temperature and solution pH were investigated, as well as the adsorption isotherms were analyzed. Results showed that the added squid melanin effectively adsorbed Pb^2＋ and Cr^6＋ in aqueous solutions. The removal rates of Pb^2＋ and Cr^6＋ were above 85.00% after adsorption of 15 min by squid melain. In addition, the removal rate of Pb^2＋ decreased with the increased adsorption temperatures, whereas, the maximum adsorption of Cr^6＋ was found at 35℃. The low adsorption capacity of squid melanin on Pb^2＋ was observed at solution pH of 5.0, and the effective solution pH for Cr^6＋ removal was in the range of 4.0 to 6.0. Furthermore, results of adsorption isotherms revealed that the adsorption characteristic of squid melanin on Cr^6＋ fitted well to Langmuir and Freundlich models. By comparison, the adsorption behavior of squid melanin on Pb^2＋ only had a good correlation with the Langmuir isotherm.
