玉米芯粉固定枯草芽孢杆菌对废水中Cr6+的吸附性能研究
Adsorption Capacity of Corncob Powder Immobilized Bacillus Subtilis for Cr6+ in Wastewater
摘要
Abstract
A microbial adsorbent was prepared using two materials,corn cob and Bacillus subtilis.Using the adsorption rate of Cr6+ in wastewater as an indicator,the effect of corn cob powder immobilized Bacillus subtilis on the adsorption of Cr6+ in wastewater was investigated under different temperature,time,dosage,and pH conditions.The optimal conditions for the adsorption of Cr6+ in wastewater by immobilized Bacillus subtilis on corn cob powder were determined through response surface methodology.The experimental results show that the immobilized Bacillus subtilis on corn cob powder has better adsorption effect on Cr6+ in wastewater at a temperature of 35℃,pH=4.7,and oscillation time of 63 minutes,with a removal rate of 89.64%.关键词
