ion exchange

基本解释

Application of ion exchange softening method, can make steam boiler feed water hardness meet eligibility criteria.
应用离子交换软化法，可使蒸汽锅炉给水的硬度达到合格标准。
Though seawater contains only three parts per billion of uranium, mostly in the form of uranyl tricarbonate, the element can be sucked out of it by ion exchange.
虽然铀在海洋中的含量只有十亿分之三，但其中大部分都以三碳酸铀的形式存在，使得铀元素可以通过离子交换吸出。
Arsenic is separated from the bismuth matrix by ion exchange method and determined by hydride generation atomic absorption spectrophotometry.
该方法用离子交换将砷同基体铋分离，然后用氢化物发生原子吸收光谱法测定。

It uses two ion exchange processes to remove the radioactive elements Cesium-134 (Cs-134), Cesium-137 (Cs-137) and Strontium-90 (Sr-90) from the seawater.

The first is a bulk removal, ion exchange process in which sodium is swapped for cesium or strontium within an inorganic, crystalline structure.

The second utilizes a highly selective media to capture more radioactive elements in the presence of ions other than sodium, such as potassium, magnesium, and calcium, also through ion exchange process.

the process in which ions are exchanged between a solution and an insoluble solid, usually a resin. It is used to soften water, to separate radioactive isotopes, and to purify certain industrial chemicals
