- who: Sofu00eda Ortegu00f3n et al. from the Department of Chemistry, Universidad de Los Andes, Cra E No19a-40, Bogotu00e1, Colombia have published the research: Magnetic Torus Microreactor as a Novel Device for Sample Treatment via Solid-Phase Microextraction Coupled to Graphite Furnace Atomic Absorption Spectroscopy: A Route for Arsenic Pre-Concentration, in the Journal: Molecules 2022, 6198 of 25/08/2022
- what: This experiment was carried out in triplicate. relative retention percentage was determined by the difference between the initial arsenic Figure 4a shows that arsenic adsorption was favored at pH values close to 6 . . .
