kellbrook Posted October 28, 2011 Share Posted October 28, 2011 what does ultrafilterable mean? example non-ultrafilterable magnesium thanks Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted October 28, 2011 Share Posted October 28, 2011 At a semi-educated guess from a very brief Google search, I think it refers to something that is easily filtered by physiological systems. I'm not 100% on that though, since it's not really a chemistry term. Link to comment Share on other sites More sharing options...
Psycho Posted October 28, 2011 Share Posted October 28, 2011 In the case of unfilterable magnesium it is defined as magnesium ions or magnesium in complex with sugars or phosphate. Link Link to comment Share on other sites More sharing options...
mississippichem Posted October 28, 2011 Share Posted October 28, 2011 Some nanoparticle solutions can't be filtered by traditional means. They'll either conglomerate and fall out of the colloidal phase our slip right through the filter. Could this be what you are talking about?

kellbrook Posted October 29, 2011 Author Share Posted October 29, 2011 (edited) so in the laboratory, is there something called an ultrafilter? or something that performs this kind of task? Edited October 29, 2011 by kellbrook Link to comment Share on other sites More sharing options...

Yes, the process is ultrafiltration. abbreviated "UF". You'll often see it mentioned together with diafiltration, abbreviated "DF", or together as "UF/DF" (say "uff duff"). I never worked with it myself, but I've had coworkers who did. Wikipedia can probably tell you more about it than I can. Link to comment Share on other sites More sharing options...

mississippichem Posted October 29, 2011 Share Posted October 29, 2011 Oh. Utrafilterable! I stupidly read "unfilterable". Disregard my hastily posted comment above. Link to comment Share on other sites More sharing options...
