Abstract
This research was undertaken to determine which metals would be suitable to be used as electrodes for the determination of the concentration of chlorine in aqueous solutions at various pH levels. Platinum, palladium, bismuth, copper and silver electrodes were constructed and tested to determine their applicability for measuring the concentration of chlorine in drinking water, waste water treatment plant effluent, and swimming pools. Buffer solutions were used which varied in pH from 7 to 8, and in cHorine concentration from 0 to 10 ppm. In addition, the potential variation over time was observed for each electrode in the solutions.
Platinum, palladium, and copper were found the most appropriate metals for the potentiometric determination of chlorine. The data obtained using these electrodes conformed with Nernstian theory. In addition, the response for palladium appeared to be affected by a variation of pH.
