【 摘 要 】

References(10)Cited-By(3)A new device, called the position-scanning spectrophotometer, which measures the concentration profiles of lightabsorbing solute species in the course of an unsteady multicomponent diffusion process, is described. Illustrative examples of application of this spectrophotometer to the coupled ternary diffusion process in the water-NiCl2-CoCl2 system and to diffusion-controlled mass transfer with an irreversible instantaneous chemical reaction between nitroso-R salt and copper sulfate are shown. These examples indicate that this spectrophotometer is a powerful means of studying complex diffusional processes in liquid phase.
