A 1 mM sodium salicylate solution in 5% (v/v) methanol was used as the mobile phase. The separation of some inorganic anions (monofluorophosphate (MFP), phosphate and iodide) was carried out in about 10 minutes. Detection was made using indirect UV detection at 290 nm. Satisfactory reproducibility of the results was obtained even after a four months period of continual use of the column. Through the evaluation of the analytical parameters, the method was linear (r = 0.999) at concentrations ranging from 10.0 to 100.0 μg mL-1 style="background-color:rgb(250, 250, 250); color:rgb(17, 17, 17); font-family:arial,verdana,helvetica,sans-serif; font-size:11.2px">.
