AbstractThe extraction process of ternary ion-association complexes of molybdenum (VI) with some polyphenols (4-nitrocatechol, 2,3-dihydroxy naphthalene) and thiazolyl blue has been investigated by using an extraction-spectrophotometric method. The optimum conditions for their quantitative preparation in aqueous medium and subsequent extraction into an organic solvent have been found. The extraction, distribution and association constants, and the recovery factors have been calculated. The composition of the complexes has been determined. A precise, sensitive and simple extraction-spectrophotometric method for determination of molybdenum in products from ferrous metallurgy has been developed.

A simple and one-pot protocol has been developed to synthesize bioactive 2-amino-4H-chromenes by using silver nanoparticles (AgNp) as a catalyst at room temperature in an aqueous medium. This method provides operational simplicity and an environment-friendly green approach. All the synthesized compounds were evaluated for antifungal activity against Alternaria alternata.
