Abstract
THE removal of particulate matter from water by mixed bed ion exchange resin columns has recently been the subject of some comment, in particular with regard to the removal of particles of iron1,2 and aluminium3 oxides from nuclear reactor loops containing water. We have been concerned with experiments with very dilute solutions, which necessitate the use of water free of suspended matter, and we have observed that this filtration can be extremely efficient. A simple intensity comparison of scattered light from ‘AnalaR’ water and from water from an ‘Elgastat’ mixed bed demineralizer, 60 cm long × 9 cm diameter, showed that at least 50 times more light was scattered from the ‘AnalaR’ water. The ratio of suspended solids in the two liquids is larger than 50, as there is present a background of scattered light which should be subtracted from the two intensities to obtain a true figure; it is very difficult to distinguish the very small amount of scattered light from the demineralized water from this background illumination.
