Zinc oxide nanoparticles were obtained by chemical precipitation method using zinc nitrate and aqueous solution of sodium hydroxide as precursors. The ZnO nanoparticles exhibited excellent photocatalytic activity for Orange-II dye degradation under visible light irradiation. ZnO nanoparticles are easy to recover and can be used upto three times without loss of...
In the present paper, synthesis of Schiff base ligands and the metal complexes are studied and compared by conventional and solvent free route. The synthesis of Schiff base ligands of amino acids (Glycine, Phenylalanine and Tyrosine) with salicylaldehyde and their mixed ligand ternary Cu(II) complexes are discussed. Other ligands are used in co-ordinaion with the ...
The present work describes the spectrochemical study of some Lanthanide (III) - ceftazidime (Ln(III)-CEFZ) complexes. The impact of the ligand environment on electronic spectrum of the lantanide ion with special reference to complexation and nature of Ln-ligand bond has been examined. The energy and intensity parameters for the complexes have also been evaluated....
Extraction of essential neem oil from neem seed were carried by soxhelt extraction and simple distillation method using different types of solvents and parameters. Physico-chemical characteristics of the extracted oil were also determined by using classical wet chemical method. Results were generated in both techniques. Soxhlet extraction using hexane has 40.35%, using...
The purpose of this work is to correlate the excess oxidant-air with the percentage of CO2 in the combustion chamber waste gas of a three-bed regenerative thermal oxidizer unit for the elimination of gaseous pollutants in a given capacity.
