The Effect of Exclusion Volume on Potentiometric Nitrate Measurement1
- J. T. Gilmour and
- H. Don Scott2
Data are presented which show that large anion exclusion volumes can occur when montmorillonitic soils, low in total salt, are extracted with water. Nitrate measurements on such extracts with the nitrate specific ion electrode reflect this exclusion volume induced error. A possible solution to the problem is suggested.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
