Ethene carboxylic acid removal from wastewater using powder activated carbon (PAC) requires a proper process parametric study to determine its optimal performance characteristics. Response Surface Methodology (RSM) is one of the advanced statistical analysis techniques for parametric studies involving a minimum number of trials. The Box‐Behnken surface statistical design of experiments was carried out with three factors, i.e., dose, w , temperature, T , and time of contact, t , between the ethene carboxylic acid and the adsorbent, while maintaining the ethene carboxylic acid concentration, C 0 = 100 mg/L, as a fixed input parameter. The performance of the Box‐Behnken design was analyzed and optimized using Design‐Expert software for ethene carboxylic acid removal onto adsorbent using a batch system. The higher values of the correlation coefficients, lack‐of‐fit greater than 4 and p values < 0.05 are in good agreement with the optimum combination of process parameters, which proves the fitness of the selected model for analyzing the experimental data.
