VISOCOLOR Chlorine
Titrimetric determination of chlorine
At a pH value of 5 – 6 free chlorine reacts with N,N-diethyl-1,4-phenylene diamine (DPD) to form a red-violet dye. In the presence of iodide ions the content of total chlorine can be determined, too. (Reaction principle is analogous to APHA 4500CL G & DIN EN ISO 9963-1)
