Green citrate sol-gel synthesis of CuMn₂O₄/Dy₂O₃ nanocomposite for efficient separation, preconcentration, and determination of Cd(II) in food and environmental samples
{{output}}
A novel CuMn₂O₄/Dy₂O₃ nanocomposite was synthesized and applied as an efficient adsorbent for the trace Cd(II) using micro solid-phase extraction (µSPE) coupled with high-resolution continuum source flame atomic absorption spectrometry (HR-CS-FAAS). The n... ...
