Determination of liquid–solid mass transfer coefficients for a spinning disc reactor using a limiting current technique

Liquid–solid mass transfer performance on a 30 cm diameter spinning disc reactor is determined by use of the limiting current technique for copper deposition at different radial locations. Values for the local mass transfer coefficient are determined for a range of liquid flow rates and rotational speeds. The experimental data is compared with a model based on diffusion into a laminar flowing film and the enhancement in performance over this model is examined.
