4.4mg L −1 and sub mg L− 1 concentrations of nitrate, bromide and iodide. These results
indicate the sensitivity of the measurement method and the time required to analyse all
five anions. The practical limit of detection is about 50mg L−1 for all of the anions
except chloride which is about 1mgL− 1.
