A NEW METHOD FOR STUDYING SELF-DIFFUSION IN LIQUIDS: SELF-DIFFUSION IN LIQUID MERCURY.
NOTTINGHAM UNIV (ENGLAND)
A new technique has been developed for measuring the selfdiffusion coefficients of liquids. Inactive and labelled samples of the liquid are contacted in a long capillary cell, and the extent of diffusion at suitable time intervals determined by means of a collimated scintillation counter. Experimental details and possible errors are discussed. The method has been tested with liquid mercury. The result agrees with the work of Nachtrieb and Petit, but is significantly lower than measurements by the capillary cell technique. Possible reasons for this are discussed. Author
