This article reports researchers at the University of Leicester have developed a technique for treating metals which could have environmental and economic benefits for a wide range of industries, including aerospace and automotive. Ionic liquids, essentially salts that are fluid at room temperature, are able to dissolve many different organic and inorganic materials, including the trivalent form of chromium, which, owing to its relatively low toxicity, is attractive for electroplating operations.
