Seek the selectivity for the transformation of 001X7 cation resin
Thread Content
May I ask: if I convert the 001X7 cation resin to the H type, which has a better exchange capacity for K, Na, Ca, Mg, Fe, and Al in water – the H type or the Na type? I’ve also heard that H-type cationic resins cannot remove Ca; if that’s the case, why? Please leave more comments, experts. This post was last edited by hesonchang214 on 2009-4-22 at 17:34.]
H-type cationic resins perform better in exchanging K and Na from water than Na-type resins, but they perform worse in exchanging Ca, Mg, Fe, and Al compared to Na-type resins. H-type cationic resins can remove Ca.
The adsorption strength of ions is related to their molecular weight and reactivity; the 001*7 resin should be able to remove calcium ions
Are there any books that can explain this issue in detail? I would like to understand the principles behind it, as well as when to use the H-type and when to use the Na-type
