Cadmium isotopic composition of biogenic certified reference materials determined by thermal ionization mass spectrometry with double spike correction

Popis výsledku v původním jazyce

A Cd-116-Cd-16 double-spike method in combination with thermal ionization mass spectrometry (TIMS) was applied to obtain cadmium (Cd) mass fractions and stable isotope compositions in seven biogenic certified reference materials (pine needles, tomato leaves, spinach leaves, lichen, mussel tissue, oyster tissue, and pig kidney). This sample set was supplemented by the analysis of two manganese nodules and one soil reference material for which the Cd isotopic data has already been reported. The intermediate measurement precision of the whole protocol as determined for the NIST SRM 3108 Cd standard solution yields an excellent value of delta Cd-114/110 of -0.005 +/- 0.029 parts per thousand (2SD, n = 47). The Cd isotopic compositions of the biogenic materials, reported as 8114/11 Cd relative to NIST SRM 3108, range from -0.52 to +0.50 parts per thousand. Plants show delta(114)/Cd-110 mean values ranging from -0.09 to +0.45 parts per thousand whereas the delta Cd-114/110 value of -0.17 parts per thousand was detected in the lichen and the values of -0.51, -0.52, and +0.47 parts per thousand were gathered for the oyster, mussel, and pig kidney tissues, respectively. The observed large variation of the delta Cd-114/110 values in the biogenic reference materials indicates a potential to use the natural mass-dependent Cd isotope fractionation in environmental, biogeochemical, and physiological studies.
