Abstract:
1. A method of analysing chemical species in a solution, the method comprising: providing an electrochemical deposition apparatus comprising a first electrode formed of an electrically conductive diamond material and a second electrode; locating the first electrode in contact with a solution to be analysed and the second electrode in electrical contact with the solution to be analysed; applying a potential difference between the first and second electrodes such that current flows between the first and second electrodes through the solution to be analysed and chemical species are electro-deposited from the solution onto the first electrode; applying a spectroscopic analysis technique comprising x-ray fluorescence elemental analysis to the electro-deposited chemical species on the first electrode to generate spectroscopic data about the electro-deposited chemical species on the first electrode; using the spectroscopic data to determine the type of chemical species electro-deposited on the first electrode; and using the spectroscopic data to determine the quantity of chemical species in the solution.
