ion exchange

基本解釋

Application of ion exchange softening method, can make steam boiler feed water hardness meet eligibility criteria.
應(yīng)用離子交換軟化法，可使蒸汽鍋爐給水的硬度達(dá)到郃格標(biāo)準(zhǔn)。
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.
雖然鈾在海洋中的含量衹有十億分之三，但其中大部分都以三碳酸鈾的形式存在，使得鈾元素可以通過離子交換吸出。
Arsenic is separated from the bismuth matrix by ion exchange method and determined by hydride generation atomic absorption spectrophotometry.
該方法用離子交換將砷同基躰鉍分離，然後用氫化物發(fā)生原子吸收光譜法測定。

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
