NOVELTY – The ultra-sensitive electrochemical sensor for copper detection has gold electrodes modified by individual layers of mercaptopropionic acid. The electrodes concentrate copper ions in solution in 5 minutes on studying the copper content of samples of mineral water. USE – For detection of copper in mineral water sample.
