Estimation of gold in serum by atomic absorption spectroscopy.
The therapeutic use of gold compounds is of considerable antiquity, as discussed by Nineham (1); it has been used for the treatment of rheumatoid arthritis since 1927 (2). Treatment in the past has been largely empirical. Until the advent of the atomic absorption spectrophotometer the estimation of gold in biological fluids by classical chemical or other methods was beyond the capability of the...
متن کاملEstimation of gold in urine by atomic absorption spectroscopy.
The gold toxicity occasionally encountered during the treatment of rheumatoid arthritis by chrysotherapy may be conveniently treated with chelating agents to facilitate the urinary excretion of gold. It is of interest to monitor this urinary gold excretion, atomic absorption spectroscopy being a convenient technique. Although serum gold concentrations may be estimated after simple dilution (1),...
متن کاملIndirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy
A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...
متن کاملNormal serum calcium levels by atomic absorption spectroscopy.
THE INITIAL STUDIES BY WILLIS (2, 3) and the more recent work of Zettner and Seligson (i) and others (4-7, 9-11) have proven the utility of atomic absorption spectrophotometry (AAS) in the clinical laboratory. However, until very recently there has been very little if any published information dealing with normal serum calcium values by atomic absorption spectrophotometry (11). The primary purp...
متن کاملMeasurement of serum lithium by atomic absorption spectroscopy.
Lithium concentrations in the serum of patients undergoing therapy with lithium salts were measured by atomic absorption spectroscopy. Serum was diluted 10-fold with water. Physiological amounts of sodium and potassium were included in the blank and standard solutions because these cations enhance the lithium signal by 2%. Calcium, magnesium, bicarbonate, sulfate, and phosphate at the concentra...
