Analysis of Polyphenols from Jacq.

Plant polyphenols have significant importance due to their potential health benefits. Jacq. is commonly found in Asia and has a long history of use in traditional medicine.

Highly sensitive determination of Co(II) ions in solutions by using modified silver nanoparticles.

In this manuscript, we report the development of a rapid and facile optic sensor for highly sensitive and selective detection of cobalt ions (Co(II)). The detection strategy was based on the specific silver nanoparticle-glutathione interaction and later on secondary interaction of this structure with cysteine and Co(II) ion. The interaction of these structures creates a new absorption band in the UV region.

Quantitative determination of glycine in aqueous solution using glutamate dehydrogenase-immobilized glyoxal agarose beads.

In this study, an enzymatic procedure for the determination of glycine (Gly) was developed by using a column containing immobilized glutamate dehydrogenase (GDH) on glyoxal agarose beads. Ammonia is produced from the enzymatic reactions between Gly and GDH with NAD(+) in phosphate buffer medium. The indophenol blue method was used for ammonia detection based on the spectrophotometric measurements of blue-colored product absorbing at 640 nm.

Simultaneous decolorization of binary mixture of reactive yellow and acid violet from wastewaters by electrocoagulation.

Dyes are common pollutants in a large variety of industrial wastewaters, and the treatment of these wastes has been extensively studied by coagulation. For the removal of pollutants from the wastewaters, different techniques have been used and electrocougulation is one of the widely used methods. This process is very effective in removing organic pollutants including dyestuff wastewater.
