A coprecipitation of copper(II) and zinc(II) from complex sulfate solutions with natural calcite was investigated. The main features of the process and mineral forms of incorporation of heavy metals in a solid phase were determined. Sequential precipitation proceeds at pH 5.3–5.5 and 6.5–7.0 ...
A new series of asymmetric salicyl-, furanyl-, thienyl- and pyrrolyl-derived ONNO, NNNO, ONNS & NNNS donor antibacterial and antifungal Schiff-bases and their copper(II) and zinc(II) metal complexes have been synthesized and characterized. IR spectra indicated the ligands to act as quartden...
The new systems are the beta-diketone-pyridyl derivative, 3-(pyridin-4-ylthio)pentane- 2,4-dione (L(1)), and its hydrazine condensation product, the pyridyl-pyrazole species 4-(3,5-dimethyl-1H-pyrazol- 4- ylthio)pyridine (L(2)). Both systems were designed for use in metal-organic ...
