The Use of a Specific Ion Electrode for Determination of Bromide in Soils¹

ABSTRACT

Bromide has desirable characteristics for use as a tracer for NO₃^- in some soil studies. However, its quantitative determination in the presence of Cl^-, which occurs in interfering quantities in many soils, requires lengthy procedures. Further, Br^- interferes with the quantitative determination of Cl^- for which concentrations may also need to be determined. To facilitate the use of Br^- as a tracer in such tests, a procedure for the rapid and accurate determination of water-extractable Br^- in the presence of Cl^- and Cl^- in the presence of Br^- was developed. These quantitative determinations over a wide range of concentrations were accomplished by use of standard curves, interference curves, and successive approximations. Bromide added to soil over a wide range of concentrations was quantitatively recovered.
