Preparation and Characterization of Mixed Ligand Complexes of Cobalt(II) and Ni(II) salt of Phthalimide with Some Oxamic Acids
Abstract: The mixed ligand complexes of oxamic acids with Co(II) and Ni(II) salt of phthalimide were prepared, where oxm= N-phenyl thio urea oxamic acid(NPTUOA),m-tolumide oxamic acid (m-TOA), N-pyrrazole oxamic acid & phth= Co(II) and Ni(II) salt of phthamlimide. These all mixed ligand complexes examined by their elemental analysis, melting points, UV-visible analysis, I.R studies, magnetic susceptibility measurements and thin layer chromatography. Elemental analysis of the complexes shows 1:2 (Metal:Ligand) stiochiometry for …

Eco-friendly Color Production for Holi Celebration: A Mini Review
Abstract: Many synthetic colours formed from chemicals have adverse effects on environment. Biocolours are nowadays used in holi festival. Colours are also becoming integral part of modern day life. Use of colours are becoming a part of our everyday life. There is need of nontoxic colours in order to remove substances like lead, cadmium, chromium and cobalt entering in the food chain. Biocolours are mainly prepared from plant origins. The current …

Review of Reactive Extraction Process for Recovery of Pyruvic Acid
Abstract: Pyruvic acid having a molecular formula (C3H4O3) is an important alpha-keto-carboxylic acid. It is mainly manufactured by biotechnological routes or chemical synthesis. There are number of applications of pyruvic acid in the industrial sector such as chemical, food, cosmetic and agriculture sector. The main problem for the production of pyruvic acid from the fermentation broth is downstream processing. The number of techniques developed to recover this acid from their aqueous …
