Determination of Cu, Zn, Ga, Ag, Cd, In, Sn and Tl in Geological Reference Materials and Chondrites by Isotope Dilution ICP‐MS

open access: yesGeostandards and Geoanalytical Research, Volume 44, Issue 4, Page 733-752, December 2020., 2020
Key Points Mass fractions for eight volatile elements (Cu, Zn, Ga, Ag, Cd, In, Sn and Tl) in 21 geological reference materials by ID‐Q‐ICP‐MS are reported. Target elements were chemically separated with a novel anion‐exchange chromatography. The intermediate precision (2s) of 2–4 replicates was < 4% and results agree with literature data.

Hydrophysical Database for Brazilian Soils (HYBRAS) and Pedotransfer Functions for Water Retention

open access: yesVadose Zone Journal, Volume 17, Issue 1, Page 1-17, 2018., 2018
Core Ideas We propose a Hydrophysical Database for Brazilian Soils (HYBRAS). Data in HYBRAS comprise 445 soil profiles, with 1075 samples of Brazilian soils. We compared the accuracy of water retention estimates based on climate‐based PTFs. In general, the Brazilian PTFs performed better than the temperate models for HYBRAS.
