Bromine, because it is stable and less volatile than chlorine, is utilized as a disinfectant in swimming pools, spas and hot tubs. As with chlorine, excessive quantities of bromine in water can be dangerous to health and can cause eye irritation.
Daily monitoring of bromine concentration prevents damage to equipment and contributes to the optimization and efficiency of the process while providing for increased user safety.
The HANNA portable bromine test kit determines the bromine level in water with efficiency. The first step involves pH adjustment of the sample to pH 6.3 by adding pH buffer. The second step consists of adding the second reagent, an indicator solution which contains DPD (N, N-diethyl-p-phenylenediamine). DPD is immediately oxidized by bromine producing a reddish color. The color intensity of the solution determines the bromine concentration.
