Nickel was complexed with BTAHQ at pH 4.0. The IL-DLLME procedure was performed by using a few mL of [C6mim][PF6] as the extractant while methanol was the disperser solvent. The Ni-enriched RTIL phase was solubilized in methanol and the absorbance at λmax 682 was directly measured against a reagent blank similarly prepared.
