Application of Ion Chromatography to the Characterization of Biological Calcium Phosphates

  • Chapter
Book cover Recent Developments in Ion Exchange

Synopsis

Biological calcium phosphates are often complex mixtures of amorphous and crystalline phases, sometimes embedded in an organic matrix. We have used ion chromatography to determine all of the major ionic constituents of the encrusting deposit on 10 urinary catheters. All contained calcium and phosphate together with magnesium and ammonium in appreciable amounts together with smaller quantities of potassium and sodium. With two possible exceptions, the deposits appear to be mixtures of crystalline struvite (MgNH4PO4.6H2O) and a poorly crystalline or amorphous, basic, calcium phosphate.
