“…The Cd mass fractions of soil reference materials were reported by NIST and IGGE, and most of the values for rock reference materials were determined by isotope dilution mass spectrometry in this study. With the exception of GSS‐1 and NOD‐P‐1, only minimal Cd isotope data for NIST SRM 2709, 2709a, 2711, 2711a, BIR‐1, and AGV‐2 have been reported (Cloquet et al , Pallavicini et al , Wiggenhauser et al , Palk et al , Imseng et al , Li et al ), and the Cd isotope values of some of the reference materials are reported for the first time in this study.…”

“…With advances in instrumentation, increasingly high precision Cd isotope measurement results have been reported using different chemical purification procedures and different instrumental analysis methods (e.g., Wombacher et al , Cloquet et al , Ripperger and Rehkämper , Gao et al , Schmitt et al , Xue et al , Li et al ). The Cd isotopes of different types of samples with low Cd mass fractions including organic materials, plants, carbonates, silicate rocks, river sediments, seawater and meteorites have been determined precisely and accurately (e.g., Rosman and De Laeter , Cloquet et al , Ripperger and Rehkämper , Gao et al , Wombacher et al , Schmitt et al , Abouchami et al , Pallavicini et al , Georgiev et al , Wei et al , Wiggenhauser et al , Wen et al , Hohl et al , John et al , Imseng et al , Li et al , Viehman et al ). The mass bias produced by the instrument has been corrected by different methods including sample‐calibrator bracketing, and the Ag doping and double spike method (Wombacher et al , Cloquet et al , Ripperger and Rehkämper , Schmitt et al , Li et al ).…”

“…The double spike technique can effectively correct isotope fractionation from chemical separation and mass discrimination of the instrument (e.g., Compston and Oversby , Galer , Ripperger and Rehkämper , Rudge et al , Schmitt et al ). Recent studies have shown that the use of double spike is beneficial for determining the Cd isotope compositions in different types of samples with low Cd mass fractions (e.g., Ripperger and Rehkämper , Schmitt et al , Horner et al , Georgiev et al , Wiggenhauser et al , Hohl et al , John et al , Imseng et al ). Schmitt et al () and Rehkämper et al () have mentioned that when choosing a Cd double spike correction method, two factors should be considered: (a) isobaric and molecular interferences, and (b) limitations imposed by the collector configuration and the maximum mass dispersion that can be accommodated by the collectors.…”

This study presents a high‐precision Cd isotope measurement method for soil and rock reference materials using MC‐ICP‐MS with double spike correction. The effects of molecular interferences (e.g., 109Ag1H+, 94Zr16O+, 94Mo16O+ and 70Zn40Ar+) and isobaric interferences (e.g., Pd, In and Sn) to Cd isotope measurements were quantitatively evaluated. When the measured solution has Ag/Cd ≤ 5, Zn/Cd ≤ 0.02, Mo/Cd ≤ 0.4, Zr/Cd ≤ 0.001, Pd/Cd ≤ 5 × 10−5 and In/Cd ≤ 10−3, the measured Cd isotope data were not significantly affected. The intermediate measurement precision of pure Cd solutions (BAM I012 Cd, Münster Cd and AAS Cd) was better than ± 0.05‰ (2s) for δ114/110Cd. The δ114/110Cd values of soil reference materials (NIST SRM 2709, 2709a, 2710, 2710a, 2711, 2711a and GSS‐1) relative to NIST SRM 3108 were in the range of −0.251 to 0.632‰, the δ114/110Cd values of rock reference materials (BCR‐2, BIR‐1, BHVO‐2, W‐2, AGV‐2, GSP‐2 and COQ‐1) varied from −0.196‰ to 0.098‰, and that of the manganese nodule (NOD‐P‐1) was 0.163 ± 0.040‰ (2s, n = 8). The large variation in Cd isotopes in soils and igneous rocks indicates that they can be more widely used to study magmatic and supergene processes.

“…This observation urges caution for studies attempting to use Cd isotope variations to trace anthropogenic Cd sources to the environment. Given the somewhat surprising nature of this result, it is emphasized that the integrity of the data are beyond reasonable doubt, with the Cd isotope methods employed here being carefully validated both as part of the current (Text S4 and Table S4) and a number of previous studies [ Xue et al , , Murphy et al , , Wiggenhauser et al , ].…”

“…The quoted precision of the Cd isotope data was estimated from the reproducibility of the bracketing analyses of matching NIST 3108 Cd‐Cd DS mixtures, which was ±1 to ±2 ε 114/110 Cd (2 SD; Table S2). Additional SRMs were analyzed to validate the accuracy and precision of the isotope measurements (Table S4 and Text S4) with results in good agreement with published values [ Yi et al , ; Wombacher et al , ; Abouchami et al , ; Wiggenhauser et al , ].…”

Stable isotope compositions can potentially be used to trace atmospheric Cd inputs to the surface ocean and anthropogenic Cd emissions to the atmosphere. Both of these applications may provide valuable insights into the effects of anthropogenic activities on the cycling of Cd in the environment. However, a lack of constraints for the Cd isotope compositions of atmospheric aerosols is currently hindering such studies. Here we present stable Cd isotope data for aerosols collected over the Tropical Atlantic Ocean. The samples feature variable proportions of mineral dust‐derived and anthropogenic Cd, yet exhibit similar isotope compositions, thus negating the distinction of these Cd sources by using isotopic signatures in this region. Isotopic variability between these two atmospheric Cd sources may be identified in other areas, and thus warrants further investigation. Regardless, these data provide important initial constraints on the isotope composition of atmospheric Cd inputs to the ocean.

A novel potentiometric approach for the sensitive detection of cadmium in real samples using modified carbon paste electrodes

The goal of this study was to demonstrate a novel potentiometric technique for the measurement of Cd(II) ion. A new ionophore called [5′‐(ethane‐1,2‐diylbis(sulfanediyl))bis(3‐phenyl‐4H‐1,2,4‐triazol‐4‐amine) (ESPTA)] was prepared and used as an electroactive material in the fabrication of new carbon paste electrode (CPE) for the quantification of Cd(II) ion. The paste was prepared by mixing ESPTA, graphite, graphene, and TCP or o‐NPOE as a plasticizer in different weight percent ratios. The developed electrodes I, II, III, and IV showed divalent Nernstian response of 29.80±0.05, 29.80±0.08, 29.86±±0.04 and 29.75±0.33 mV decade−1 over the concentration ranges of 1.0×10−5–1.0×10−1, 1.0×10−8–1.0×10−1, 1.0×10−6–1.0×10−1 and 1.0×10−7–1.0×10−1 mol L−1 with percentage of (2.65 ESPTA: 66.32 graphite: 31.03 TCP), (2.65 ESPTA: 13.27 graphite : 53.05 graphene : 31.03 TCP), (2.75 ESPTA: 68.68 graphite: 28.57 o‐NPOE) and (2.75 ESPTA: 13.74 graphite : 54.94 graphene : 28.57 o‐NPOE), for electrodes I, II, III, and IV, respectively. In order to improve the performance characteristics of electrodes I, II, III, and IV, response time, the effect of temperature, and pH were examined. The electrodes showed high selectivity for Cd(II) over different mono‐, di‐ or trivalent cations. These modified electrodes were applied for the determination of the concentration of Cd(II) in different real samples like Nido Milk, juice extractions and tap water samples with high percentage recovery. The F‐ and t‐test values showed that there is no statistically significant difference between the results obtained and those from the stated method of inductively coupled plasma. Low standard and relative standard deviation values, good percentage recovery, and modest detection and quantification limitations were all displayed by the electrodes. The outcomes showed the potentiometric method‘s effectiveness in detecting Cd(II) in actual samples and its potential for use in routine analysis.
