Rapid analysis of nickel in serum and whole blood by electrothermal atomic absorption spectrophotometry.

IUPAC reference method for analysis of nickel in serum and urine by electrothermal atomic absorption spectrometry.

Blood nickel concentrations in patients with stainless-steel hip prostheses.

Nickel concentrations were analyzed by electrothermal atomic absorption spectrophotometry in serum and whole blood specimens from patients 9 to 15 years after unilateral (N = 11) or bilateral (N = 2) hip arthroplasty. The hip prostheses were of the "Charnley" or "TR-28" (metal-to-plastic) types, fabricated of stainless-steel (14 to 16 percent Ni) with polyethylene acetabular cups. In 12 of the ...

Determination of nickel in biological samples prepared by microwave dissolution using electrothermal atomic absorption spectrometry after extraction with l,Sbis[phenyl-( 2-pyridyl) methylene] thiocarbonhydrazide

An electrothermal atomization atomic absorption spectrometric method for the determination of traces of nickel atIer extraction of the metal into methyl isobutyl ketone containing 1,5-bis[phenyl(2-pyridylhnethylene] thiocarbonhydrazide is suggested. The chief advantage of the method lies in its maximum allowable aqueous-to-organic phase volume ratio of 37. The method was applied to the determin...

Determination of arsenic in biological fluids by electrothermal atomic absorption spectrometry.

A procedure for the determination of the total content of arsenic in urine, serum and blood by electrothermal atomic absorption spectrometry (ETAAS) is described. Zeeman correction is used to compensate the high background signals. The samples are diluted (1 + 1 for urine and 1 + 3 for both serum and blood samples) in a medium containing 0.1% w/v Triton X-100 before being introduced directly in...

Hypernickelemia following coronary arteriography, caused by nickel in the radiographic contrast medium.

Meglumine diatrizoate ("Renografin-76", a radiographic contrast medium) contains sufficient nickel to cause hypernickelemia in patients after coronary arteriography. Nickel analyses by electrothermal atomic absorption spectrophotometry showed that nine lots of "Renografin-76" (760 g of meglumine diatrizoate per L) contained 144 +/- 44 micrograms Ni per L. Serum Ni concentrations became elevated...
