The behavior of halogen ions in alkaline-earth metal oxides+halogenide+molten slag of scales was investigated.

研究了碱土金属氧化物+卤化物+氧化铁熔渣中卤离子的行为。

Orthophosphite ions produced by oxidation of hypophosphite in an electroless nickel plating bath can be removed by precipitation with an alkali metal or alkaline earth metal cation such as calcium.

在无电镀镍浴中因次磷酸根氧化而产生的亚磷酸根离子，可以通过碱金属或碱土金属阳离子如钙的沉淀作用而去除。
