C,N-pyridylpyrazole-based ligands: Synthesis and preliminary use in metal ion extraction
The synthesis of new N-donor pyridylpyrazole ligands with a functionalized arm is described. The complexation capabilities of these compounds towards bivalent metal ions (Hg2+, Cd2+, Pb2+, Cu2+, and Zn2+) and alkali metal ions ( K+, Na+, and Li+) were investigated using the liquid-liquid extraction process. The percentage limits of extraction were determined by atomic absorption measurements.
