## Discussed is the use of rotating cylinder and disc electrodes to study mass transfer in cryolitic melts. In particular the effect of a thin liquid film at the surface of a rotating cylinder on the value of the dilIuslon coefficient deduced from the experiments is described. The thinness of the

โฆ Synopsis
The diffusion coefficient of aluminum in mercury was measured over a concentration range ofo.9 to 14 mM. It was found to increase with increasingcodcentration from 1.2 x 10m5 to 1.9 x 10m5 cm2 seC'.

The objective of this paper is to present a new method of measuring oxygen diffusion coefficients with membrane-covered polarographic oxygen electrodes and to assess its applicability to viscous polymeric solutions of sodium carboxymethylcellulose (CMC), dextran and polyethylene glycol (PEG). The re
