响应曲面优化法合成CTMAB-膨润土吸附剂
Preparation of CTMAB-bentonite adsorbent with response surface methodology
摘要
Abstract
Preparation of the CTMAB-bentonite wastewater adsorbent based on the modification of cetyltrimethylammonium bromide (CTMAB) with response surface methodology (RSM) was investigated.Based on the modification of CTMAB,the optimal preparation parameters of CTMAB-bentonite determined by response surface methodology (RSM) technology were found to be as follows:CTMAB dosage of 19.5％,reaction temperature of 70.5 ℃,reaction time of 1.8 h and pH of 6.7,and the quadratic experimental fitting model (R2 =0.9757) was also obtained.The experimental values (92.6％) of removal by CTMAB-bentonite obtained under the predicted optimal conditions by confirmation experiments closely agreed with the results (94％) obtained from RSM and hence validated the findings of response surface optimization model.The method provides a basis for the synthesis of modified bentonite adsorbent and its use in wastewater treatment and environmental restoration.关键词
