Abstract
A method for recovering catalytic metals from fluids containing catalytic metal colloids. Fluid compositions such as rinse solutions or dragout baths containing catalytic metal colloids are passed through a filter that entraps catalytic metal colloids on the filter. The catalytic metal colloids have a high affinity for the filter in contrast to other components of the fluids. The other components of the fluids pass through the filter while the catalytic colloids concentrate on the filter. The filter containing the catalytic metal colloids is burned, and the catalytic metal is retrieved. The method is economically efficient and environmentally friendly.
