抄録
We have developed a new analysis method for high free-chlorine concentration using anodic current. The measurement was carried out using linear sweep voltammetry with a platinum disk electrode. An oxidation wave that was concentration dependent at about 1100 mV vs Ag/AgCl was observed, and a good linear relationship in the concentration range of 0.1–12.0 mmol$\cdot$dm-3 (Cl) was obtained between the oxidation peak current and concentration. This method seemed to be very useful for the analysis of high free-chlorine concentration.
