Spectroscopic techniques are being increasingly applied to augment electrochemical studies and provide unequivocal identification of species formed at mineral surfaces in flotation systems. These include X ray photoelectron, Fourier transform infrared spectroscopy and, more recently, surface enhanced Raman scattering spectroscopy. The progress that has been made in the application of electrochemical measurement to monitor and control flotation plants is also considered.展开更多

However, traditional methodologies for the synthesis of nitriles are limited to harsh reaction conditions. Herein, we report a new and efficient access to aryl nitriles by an electrochemical synthesis. Compared with the conventional synthetic methods, this electrochemical synthesis is more environmentally friendly and easier to handle.展开更多
