摘要
文章重点研究了D301大孔树脂在浓海水体系中提溴的应用。考察了该树脂最大吸附量、吸附平衡时间、吸附动力学和吸附热力学行为;同时对吸附洗脱速率、还原剂及其用量、洗脱剂及其用量等工艺参数进行了优化,溴的总回收率可达85%以上。
In this paper,an experimental research on extracting bromine from brine using macro-porous resin D301 had been made.The maximum amounts of adsorption,adsorption balance time,adsorption isotherm and adsorption dynamics were studied.Further more,the influence of some technological parameters,such as adsorption flow rate,reductants and their dosage,eluants flow rate for extraction of bromine was examined.The overall yield of bromine reached over 85%,
