Study on Contaminated Soil Employed Hettich ROTANTA460 Benchtop Centrifuge
The Journal of Analytical Methods in Chemistry published a study entitled “Effects of Iron Concentration Level in Extracting Solutions from Contaminated Soils on the Determination of Zinc by Flame Atomic Absorption Spectrometry with Two Background Correctors” by Christophe Waterlot, AuréliePelfrêne and Francis Douay. Hettich’sROTANTA460 benchtop centrifuge was used in the studyto separate water-soluble metal ions from kitchen garden soils.
For their research, scientists used an atomic spectrometer with an auto-sampler to determine zinc and iron concentrations in agricultural field and kitchen garden soil samples.The contaminated soils were then removed, and the solid soil residue was centrifuged. By running the Hettich ROTANTA 460 at 4,530 rpm for 20 minutes, the researchers were able to separate the necessary extracts from the residue for further study.
The study found that the high-speed self-reversal (HSSR) method was a “promising approach” for efficiently monitoring zinc concentrations in samples containing iron. The authors described HSSR as “simple, fast and interference-free,” a method that “allows zinc determination at the pbb level in the presence of large amounts of iron with high stability, sensitivity, and reproducibility of results.”
Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on thedetection and monitoring of zinc concentration in samples containing iron. The Hettich ROTANTA 460 is a high-capacity, high-throughput, safe, quiet and reliable centrifuge that is suited for most applications.
