- W4386238712 abstract "The present work is dedicated to the very important area of analytical chemistry—extractionphotometric determination of ions from a solid phase. We carried out studies on the extraction of nickel picrate (NiPik2) from the solid phase using solutions of tetrahalobicyclic reagents of the acetylene series with a dicarbonyl bridge in the side chain (L1, L2, L3, L4) of chloroform. New organic ligands were synthesized and their physicochemical properties - melting point, molecular weights, as well as their optical density studied. A new technique for the extraction-photometric determination of the nickel ion from the solid phase was developed. It found that new organic reagents (L1-L4) exhibit high extraction ability (0.11-0.64 mg/l) of Ni ions from the solid phase. When comparing the extraction activity of the studied reagents, it was revealed that the ability to extract organic ligands of tetrahalobicyclic reagents (L1-L4) changes in the following order: L4> L3> L1> L2. Magnetic field increased nickel extraction by 3-4%." @default.
