Guest Tazman Posted April 12, 2005 Share Posted April 12, 2005 Hey, just wondering if any of you could give me a hand with some calculations. I was just carrying out the Vanadomolybdate phosphoric acid method for orthophosphate in wastewater. I don't know how to convert mg/L PO4 3- to mg/L P or to mg/L PO4 3- -P. Just wondering if any of you have a quick calculation for converting this... Link to comment Share on other sites More sharing options...
budullewraagh Posted April 12, 2005 Share Posted April 12, 2005 just use percent masses... phosphorus is ________% of PO4-3 thus, you multiply that percent, converted to a decimal by the amount of phosphate Link to comment Share on other sites More sharing options...
Guest Tazman Posted April 13, 2005 Share Posted April 13, 2005 Yeah, i got that as PO4, i don't know what to do with the 3- valence, is this not used...? Link to comment Share on other sites More sharing options...
budullewraagh Posted April 14, 2005 Share Posted April 14, 2005 the extra electrons add a negligible amount of mass Link to comment Share on other sites More sharing options...
