Biosorption of Pb2+ from Natural Water using Date Pits: A Green Chemistry Approach
Removal of Pb2+ ions from aqueous solutions by adsorption onto Date Pits (DP) has been investigated. The date pits (sorbent) may represent an environmental problem. The characteristic parameters
Synthesis, spectroscopic and the biological activity studies of thiosemicarbazones containing ferrocene and their copper(II) complexes
Two Schiff bases, 1-acetylferrocene thiosemicarbazone (HL1) and 1,1′-diacetyl-ferrocene dithiosemicarbazone (H2L2) and their copper(II) complexes were prepared and characterized by elemental
Transition-metal complexes of the macrocyclic ligand 5,7,12,14-tetra-methyl- 1,4,8,11-tetra-azacyclotetradeca-4,11-diene
The macrocyclic ligand 5,12-dimethyl-1,4,8,11-tetra-azacyclotetradeca-4,11-diene (L1) has been prepared as its dihydroperchlorate salt by the reaction of ethane-1,2-diamine monohydroperchlorate with
Chromatographic separations of diastereoisomers of the 5,7,12,14-tetramethyl-1,4,8,11 -tetraazacyclotetradeca-4,11-dienenickel(II) cation, and characterization of the nickel(II) complex of the new
Planar nickel(II) complexes of different macrocyclic tetraazacyclotetradeca-4,11-diene ligands and diastereoisomers which differ in chiral carbon configurations have been separated by cation-
Ligating behavior and metal uptake of N‐sulphonylpolyamine chelating resins anchored on polystyrene‐divinylbenzene beads
Amberlite XAD-2 has been functionalized by coupling through –SO2-with ethylenediamine, propylenediamine, and diethylenetriamine to give the corresponding polyamine chelating resins I–III. The solid
Axial additions in nickel(II) complexes of (5SR,7RS,12RS,14SR)-tetra-methyl-1,4,8,11-tetra-azacyclotetradecane (Lα) and crystal-structure analysis of the planar orange and octahedral violet
Reduction of the nickel(II) complex of C-meso-5,7,12,14-tetramethyl-1,4,8,11-tetra-azacyclotetradeca-4,11-diene with NaBH4 gives predominantly the nickel(II) complex of the title ligand, Lα. Both
Spectral, thermal, molecular modeling and biological studies on mono- and binuclear complexes derived from oxalo bis(2,3-butanedionehydrazone)
TLDR
Oxalo bis(2,3-butanedionehydrazone) structure was proved by X-ray crystallography and it was proved that the presence of two metals stabilized the complex more than the mono metal.
