A simple and sensitive sequential injection spectrophotometric procedure is proposed for the determination of trace amounts of iodide in pharmaceutical preparations The method was based on the catalytic effect of iodide on the (tetra base) 4,4′-methylene bis(N,N-dimethylaniline)chloramine-T reaction in acidic solution The method involves a sequential aspiration of 255 μl sample/standard followed by 170 μl tetra base and then 128 μl chloramine-T solutions into a carrier stream to be stacked inside a holding coil and flow reversed through a reaction coil towards a detector. The resulting colored compound was measured at 600 nm using an UV/Vis-spectrophotometer. All the parameters that affected the reaction were evaluated and the calibration curve was linear over a range of 0.1-6.0 μg l-1 of iodide concentration with detection limit of 0.05 μg l-1. A sample throughput of 80 samples per h and relative standard deviation of less than 2.0% was achieved. The method was successfully applied for the determination of iodide in three different samples (tablets).
