Abstract

Adopting the method of coprecipitation，magnesium aluminum hydrotalcite and EDTA intercalated hydrotalcite was compounded． The paper compared and analyzed EDTA intercalated hydrotalcite and magnesium aluminum hydrotalcite on the adsorption of Cd2 + and influence factors，obtained the best synthesis conditions of EDTA intercalated hydrotalcite and the best adsorption conditions． Results showed that the best synthesis conditions of EDTA intercalated hydrotalcite were: pH of 6，time of 1h， temperature of 50 ℃ and the best adsorption conditions were: Adsorbent additive amounts of 1. 0 g /L，time of 50 min， pH of 6，temperature of 50 ℃．
