摘要：

Chromium(VI) reduction has been carried out by a variety of molecules of cellular and soil importance, such as thiol containing ones, ascorbic acid, saccharides and their derivatives, and nucleotides and their components using absorption spectroscopy. Based on the absorption data, the reductive abilities of these molecules have been obtained and the trend has been found to be ascorbic acid > thiols >> saccharides > nucleotides.
