The synthesis of two new C,C-pyridylpyrazole isomers with a functionalised arm is described. The complexation capabilities of these ligands compared to their homologues towards bivalent metals (Hg2+, Cd2+, Pb2+, Cu2+, Zn2+) and alkali metal ions (K+, Na+, Li+) were investigated using a liquid–liquid extraction process. The percentage limits of extraction were determined by atomic absorption measurements.
本文介绍了两种具有官能化臂的新型 C,C-吡啶基吡唑异构体的合成过程。采用液-液萃取工艺研究了这些配体与其同系物相比对二价金属(Hg2+、Cd2+、Pb2+、Cu2+、Zn2+)和碱金属离子(K+、Na+、Li+)的络合能力。原子吸收测量法确定了萃取的百分比极限。
