Ethyl Maltol as a New Ligand for Spectrophotometric Determination of Iron

     In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...

Removal of Cd(II) ions from contaminated water by a new modified magnetic chitosan nano composite

Magnetic chitosan nanocomposites are one of the more recent advanced groups of adsorbents used to remove contaminants from waste water. In this research, N- Nicotinyl-N', N"-bis (Hexamethylenyl) phosphoric triamide (HE) was used as an additive to form a new nanocomposite with the structure of chitosan / 5% Fe3O4 Nps/10% HE resulting in the highly efficient removal of Cd(II...

Vanadium Complexes with Maltol and Deferiprone Ligands: Synthesis, Characterization and In vitro Antiproliferative Activity toward Different Cancer Cells

In a systematic effort to identify a potent antiproliferative agent, four complexes of vanadium containing maltol and deferiprone ligands were synthesized and evaluated for their cytotoxic activity against five human and animal cancer cell lines, including human breast cancer cells (MCF-7), human cervix epithelial carcinoma (HeLa), human colon cancer cell line (HT-29), human leukemia cell line ...

Synthesis, Characterization and Antibacterial Activity of Cu(II), Zn(II) Ternary Complexes with Maltol and Glycylglycine

Ternary complexes of copper(II) and zinc(II) metal ions with the ligands maltol; 3-hydroxy-2-methyl-4H-pyrone (MA) and glycylglycine (GG) have been synthesized and characterized by IR, H NMR, UV-Visible, mass spectra and TGA techniques. The complexes have been screened for antibacterial activity and the results are compared with the activity of free ligands. Increased activity of ternary comple...
