Introduction: Bisphenol A is an aromatic compound that has many applications in various industries and is known as persistent pollutants. The aim of this study was to investigate bisphenol A removal by using activated carbon and shell eggs from aqueous solution by response surface experimental designs. Materials and Methods: In this study, activated carbon and eggshell were used as adsorbents. The adsorbents were prepared using standard methods and then were sized. The variables were pH, retention time, concentration bisphenol A and adsorbent dose. All experiments were performed by standard methods, and sample size determined by Box Behnken method. Results: The results showed that adsorption efficiency of both adsorbents increased with increasing in time, BPA concentration and lower pH. Maximum adsorption of activated carbon and eggshell was 92 and 33 percent, respectively. The maximum of adsorption rate was occured at the 120 min retention time. ANOVA statistical test data showed that the surface response model had statically significant liner relationship in the case of activated carbon and liner, square and interaction in the case of eggshell. Conclusion: Bisphenol adsorption by the eggshell adsorbent is low and insignificant compared to activated carbon. Activated carbon is a good adsorbent for bisphenol A.
