Se propone un modelo polinomial, expresado en variables codificadas y naturales, para predecir la cantidad de arsénico remanente al efectuar la extracción de dicho contaminante en medio acuoso empleando quitosano como medio adsorbente. Se aplica el Método de Superficie de Respuesta (MSR) considerando las condiciones de pH, tiempo de contacto, concentración de arsénico y concentración del adsorbente (quitosano) para proponer las condiciones óptimas en las que aumenta la remoción de arsénico. El modelo polinomial propuesto presenta una buena aproximación, pues el coeficiente de determinación obtenido es de 0.9983. Se presentaron curvas de nivel y análisis residuales para la validación del modelo. Este trabajo pretende ser de ayuda para la predicción de arsénico remanente y así disminuir la cantidad de experimentos a realizar en el análisis de extracción de arsénico mediante quitosano.
