The main and interactive effects of two various experimentally controlled environmental factors namely, initial nitrate concentration and time of reaction were investigated through the model equations designed by a two-level full factorial design in a shake-flask system. The results predicted using factorial regression model showed high values of regression coefficients (R^{2} = 0.959) showing good agreement with experimental data. Main and interacting effects of different process parameters on the response (amount of nitrate removal adsorbed) were found. The maximum adsorption of 24 mg g^{–1} achieved at initial concentration of 200 mg L^{–1} and reaction time of 50 min.]]>WHO.,2006Romano, N. and C.
