摘要
A kit for determining residual chlorine or chloramine amount of a sample; comprising: a means for containing a PVA solution as an indicator, and another means for containing a reducing indicator. Said reducing indicator would be oxidized by a reaction with residual chlorine or chloramine and said PVA indicator induces a dye by reaction with oxidized compound such as free iodine; wherein intensity of said dye would be changed depending upon the residual chlorine or chloramine amount of the sample.
