WebSeparation of lanthanoids by ion-exchange method is based on the fact that radii of hydrated lanthanoid ions increase with increasing atomic number. Thus, when a solution … WebCation-exchange capacity (CEC) is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules (cations), but allow these to exchange with other positively charged particles in the surrounding soil water. This is one of the ways that solid …
The functional groups that are responsible for the ion exchange
WebThe ion exchange in water softening, is a process that involves the exchange of the hardness minerals in water, chiefly calcium and magnesium, for sodium minerals. The exchange is possible because the minerals are ionic in nature, which means they have an electrical charge. The ion exchange process is based on the fact that like charges repel ... WebSerban C. Moldoveanu, Victor David, in Essentials in Modern HPLC Separations, 2013 General Comments. Various aspects related to ion-pair chromatography were presented previously. The mechanism was discussed in Section 5.2, and details about the mobile phases used for ion pairing were given in Section 7.7.Ion pairing is a common … dynamics level up edge
