COMPLEXATION AND ANTIBACTERIAL STUDY OF 1,3,4-OXADIAZOLE DERIVATIVE
Abstract: New metal complexes of Zn(II),and Ni(II) have been synthesized by reacting metal solutions with the ligand 2,5-substituted 1,3,4-Oxadiazoles in alcoholic medium. Molecular formulae of the complexes were determined and are further characterized by IR spectroscopy, magnetic susceptibility and molar conductance studies. Since two nitrogen atoms coordinate to the metal center, the ligand is termed as bidentate ligand.KEY WORDS: Complexes, Ligands, Transition metal complexes, Oxadiazoles.

Tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and Magnesium oxide Used to Control the Corrosion of Aluminium in Chloride ions Environment
Abstract: Chloride ions interact with aluminium in marine atmosphere to form corrosion cell. Due to this corrosion reaction occurs on their surface, aluminium is oxidized into Al3+. The corrosion reaction accelerates deterioration in metal and it produces galvanic, pitting, stress, crevice, intergranular corrosion. Chloride ions decrease internal and external strength of aluminium metal. It is a very important metal so used in different appliances for e.g. road, water, air transports, housing, …

THERMODYNAMICS OF HEAVY METALS (Hg2+, Cd2+, Fe2+AND Ni2+) ADSORPTION USING BOILER FLY ASH
Abstract: The effect of temperature on the adsorption of heavy metals, Hg2+, Cd2+, Fe2+ and Ni2+ using unactivated boiler fly ash (an agricultural waste) was investigated. The results showed that Hg2+ and Cd2+ ions were mostly affected by increase in temperature because their sorption rate decreased at high temperature. At the temperature of 273 K and 383 K, the amount of Hg2+ adsorbed (mg/g) by the unactivated boiler fly ash was …
