First,brine is reacted with ammonium hydrocarbonate to obtain the sodium hydrocarbonate and the ammonium chloride solution,and then filtrated.

卤水制备纯碱分两步进行,第一步用卤水、碳酸氢铵反应得到碳酸氢钠微溶析出和氯化铵溶液,过滤。

In the past, a 0.13% water solution (1:750) of Zephiran Chloride (benzalkonium chloride solution, NF) was used successfully.

在过去，曾经成功地使用过氯化苄基.二甲基.烷基铵（杀藻胺，NF）的0.13的水溶液(1:750)。

An alternate procedure is to soak the affected areas in an iced 0.13% water solution (1:750) of Zephiran chloride (benzalkonium chloride solution, NF).

一个替代程序是用氯化苄基.二甲基.烷基铵（杀藻胺，NF）的0.13的冰水溶液(1:750)来浸泡患处。
