Simultaneous extraction and colorimetric detection of ions using gel electromembrane extraction technique
A total integrated electrocolorimetric sensing approach consisting of gel-based electromembrane extraction and colorimetric detection in a one-step process was developed. This system was designed using colorimetric reagents pre-added to the agarose gel for the determination of the following two model analytes: iodide for negative ions and nickel for positive ions. In this system, when a …
