A review of, and improvements to, the techniques of trace element analysis of raw water for home dialysis.
The optimum operating conditions for the measurement of aluminium and iron concentrations in water by atomic absorption spectrometry have been determined experimentally. The characteristics of an ion-selective electrode for the measurement of fluoride have also been investigated. Contrary to other work, the addition of acid to samples did not improve their storage stability, although the acid-washing of polyethylene containers is recommended for the storage of water.
