在盐水中加入碳酸钠溶液，使其和盐水中的Ca2+反应，生成不溶性的碳酸钙

在盐水中加入碳酸钠溶液，使其和盐水中的Ca2+反应，生成不溶性的碳酸钙沉淀，其反应式如下：
Na2++CO32-→CaCO3 ↓
为了将Ca2+除净，碳酸钠的加入量必须超过反应式的理论需要量，本工艺碳酸钠的过碱量200~400mg/l。

結果 (英文) 1:

Adding sodium carbonate in the brine solution, it and saline ca2 reaction, the formation of insoluble calcium carbonate precipitates, and the following reaction formula:
NA2 CO32-→ CaCO3 ↓
To ca2 Ex, added in an amount of sodium carbonate must exceed the theoretical requirement of the reaction formula, the sodium carbonate of the present process over the amount of the base 200 to 400mg / l.

結果 (英文) 2:

In brine joins the sodium carbonate solution, make its and saline in the Ca2 reaction, formation of insoluble calcium carbonate precipitation, the reaction type is as follows: Na2 CO32- → CaCO3
.
in order to apply Ca2 inter net, the amounts of sodium carbonate must exceed the reactive theory demand, the process of sodium carbonate. Alkali 200~400mg/l.

結果 (英文) 3:

In the brine by adding sodium carbonate solution to enable it and Ca2 reactions in brine, generates insoluble calcium carbonate precipitate, their reaction is as follows:
Na2 CO32-→ CaCO3 ↓
NET Ca2, sodium carbonate added amount must be over reactive theory requirements, this process of sodium carbonate alkali 200~400mg/l.
