Serum and dialysate aluminium concentration of dialysed patients with chronic renal failure determined by atomic absorption spectrometry with a graphite furnace.
We investigated the aluminium content in water, in solutions for haemodialysis and in serum of patients, under regular haemodialysis using flameless atomic absorption spectroscopy with l'Vov platform. The aluminium content found for tap water was 6-36 micrograms/l. After deionization the aluminium content was negligible. The dialysis bath, prepared with deionized water from a concentrated solution with 30 micrograms/l of aluminium, also showed a negligible amount of aluminium. The results obtained showed that patients who take aluminium orally have predialytic aluminium serum levels between 14 and 68 micrograms/l and between 10 and 66 after dialysis. For patients who do not take aluminium orally, the corresponding values were 12-27 and 12-24. No correlation was found between age, sex, years of dialysis and aluminium serum levels.
