Ionic liquid-based dispersive liquid–liquid microextraction (IL– –DLLME) coupled with high performance liquid chromatography (HPLC) with UV detection was developed for the simultaneous extraction and determination of nickel, cobalt, copper and zinc ions. In the proposed approach, salophen (N,N'-bis(salicylidene)-1,2-phenylenediamine) was used as a chelating agent, the ionic liquid, 1-hexyl-3-methylimidazolium hexafluorophosphate, and acetone were selected as extracting and dispersive solvents… CONTINUE READING
