Process Modeling of CuO/Zeolite Preparation for COD_C_rRemoval from Acid Bright Red GR Wastewater

Abstract:

The study on CuO/zeolite preparation for COD_r removal from acid bright red GR wastewater was carried out. The optimal process parameters,with zeolite/copper nitrate solution ratio of 1:4 g/mL, copper nitrate solution concentration of 1.0mol/L, calcining temperature of 400°Cand calcining time of 5 h, were determined by single test method .The CuO/zeolite prepared under the optimal conditions obtained high COD_Cr and chroma removal rates with more than 87%and 99,9%,respectively.The process model of CuO/zeolite preparation was established by response surface methodology. The model was proved to be reliable and accurate and its theoretical values were very close to the the actual test values with absolute relative errors ranged from 0.00% to 1.49%, which can be used to predict, adjust and control the process conditions of CuO/zeolite preparation for getting desired COD_Cr removal rate.
