A Comparative Study on the Calibration of Ozone Concentration with Three Potassium Iodide Methods

This paper introduces a modifed geatral potassium method for calibration of ozone concentration. Comparative tests with neutral potassium iodide and boric acid-potassium iodide methods indicate that this method has good accuracy, stability, reliability, and interference-free feature. It is widely applicable to most environmental monitoring in laboratory.
