G. Cappelli et al., LEACHING AND CORROSION OF POLYVINYL-CHLORIDE (PVC) TUBES IN A DIALYSIS WATER DISTRIBUTION-SYSTEM, International journal of artificial organs, 18(5), 1995, pp. 261-263
PVC tubes, from the dialysis water distribution system of a 14 and a 7
year old plant, were analysed by scanner electron microscopy (SEM) an
d X-ray microanalysis (EDAX). Results showed that the leaching of mate
rial occurs depending on time of use. The phenomenon does not modify t
he chemical composition of the material. Results suggest that PVC alte
rations, induced by time, could support bacterial proliferation thus r
educing the quality of dialysate.
