摘　　要：用自制的新型吸附剂从浓氢氧化钠溶液中吸附分离氯化钠，确定了吸附时间、碱液浓度、吸附剂用量、吸附温度等因素对吸附的影响．结果表明，该吸附剂对浓碱溶液中的氯化钠有良好的吸附分离效果，且容易洗脱，重复使用10次以上仍具有较好的吸附性能．Adsorption of NaCl in 50% NaOH solution was studied with a new adsorbent whichwas prepared in our laboratory. The effects of the NaOH concentration, adsorptive temperature,adsorptive time, amount of adsorbent on the adsorption capacity were investigated respectivelyExperimental results showed that the new adsorbent was efficient in NaCl adsorption in highconcentration NaoH solution, and can be regenerated easily The adsorbent displayed goodadsorptive performance after it was used more than ten times.
