Arsenic is commonly found in seafood, and the toxicity of different speciation varies widely. Therefore, there is an urgent need to reduce the content and analyze the speciation of arsenic to improve the safety of seafood. In this study, arsenic was removed from Chlamys farreri by adding ferric ions and sodium citrate or reducing the salinity of seawater. Then, the speciation of arsenic was analyzed. The results showed that the removal rates of arsenic were 20％, 23％, 24％ and 18％ when C. farreri individuals were treated with 0.1 g L?1 Fe3+, 0.4 g L?1, 0.6 g L?1 sodium citrate or decreasing seawater salinity to 17 within 48 h, respectively. Furthermore, it was detected that the arsenic speciation in the C. farreri was mainly polar arsenic, and among the polar arsenic was mainly arsenic betaine. These results indicated that the removal of arsenic can be achieved by adding the removal agent or changing the seawater salinity under the experimental conditions. The speciation of arsenic did not change during the removal process and it was mainly excreted in the speciation of arsenic betaine.
