三羟甲基乙烷中甲酸钠的含量是影响产品性能的重要指标。本文采用电渗析方法代替离子交换树脂法脱除三羟甲基乙烷中的甲酸钠,考察了操作电压、淡室初始浓度、淡室流速、浓室初始浓度等操作条件对脱盐效果的影响。结果表明:操作电压为8V,淡室浓度0.15mol/L,淡室流速0.529cm/s,浓室初始浓度0.01mol/L甲酸钠溶液的条件,脱盐率达到95%,电渗析可有效用于三羟甲基乙烷中甲酸钠的脱除。从环境保护和资源消耗方面考虑,电渗析法优于离子交换树脂法用于脱除三羟甲基乙烷中的甲酸钠。
三羥甲基乙烷中甲痠鈉的含量是影響產品性能的重要指標。本文採用電滲析方法代替離子交換樹脂法脫除三羥甲基乙烷中的甲痠鈉,攷察瞭操作電壓、淡室初始濃度、淡室流速、濃室初始濃度等操作條件對脫鹽效果的影響。結果錶明:操作電壓為8V,淡室濃度0.15mol/L,淡室流速0.529cm/s,濃室初始濃度0.01mol/L甲痠鈉溶液的條件,脫鹽率達到95%,電滲析可有效用于三羥甲基乙烷中甲痠鈉的脫除。從環境保護和資源消耗方麵攷慮,電滲析法優于離子交換樹脂法用于脫除三羥甲基乙烷中的甲痠鈉。

The content of sodium formate in trimethylolethane is one of the important indicators for product performance. Electrodialysis instead of ion exchange resin was used to remove sodium formate from trimethylolethane. The influence of operating conditions, such as operating voltage, initial concentration in dilute chamber, flow rate of dilute chamber, initial concentration in concentrated chamber on desalination effects were investigated. Desalination ratio could reached 95%at operating voltage 8V, dilute chamber initial concentration 0.15mol/L, dilute chamber flow rate 0.529cm/s, initial sodium formate concentration in concentrated chamber 0.01mol/L. Electrodialysis could be used to remove sodium formate from trimethylolethane effectively. For environmental and resource consumption concerns, electrodialysis is better than ion exchange resin for removing sodium formate from trimethylolethane.
