Disclosed herein is a method for detecting copper(II) in a liquid sample. The method generally comprises contacting a liquid sample, such as water, with a chromogen, such as TMB, in the presence of a suitable halide, such as chloride or bromide, and an oxidizer, such as hydrogen peroxide; and detecting a color change of the chromogen. A color change signifies the presence of copper in the sample. Compositions and kits are also provided. The presence of said suitable halide was found to amplify the detection signal. |
