A new tripodal ligand 2, 4, 6-Tris (N-Salicylidenehydrazino)-s-Triazine (L) was synthesized by the condensation of salicylaldehyde with 2, 4, 6-tris-(hydrazine)- s-triazine(THSTZ) in acetonitrile. Copper complex of the ...

The tropical genus Erythril1a, which belongs to the family Leguminosae (sub-family Papilionoideae), locally known as "Korch" (Amharic) and "Wolensu" (Oromo) has folk medicinal uses such as in the treatment of stomach ...

An arnperometric system based on a carbon paste electrode modiri ed with Mn02 was in vestigated as a sensor for glucose in flow-injec tion analysis ( FIA). Enzymatic ox idation of glucose and catal yt ic ox idation of ...

Using the voltammetric senor which is constracted in our laboratory and the membrane stabilized interface between two immiscible electrolyte solution in a flow injection system the transfer of anions (CIO ,NO & 01 land ...

Acrylamide or 2-propene amide is an organic compound formed in French fries, potato crisps, bread and coffee when they are fried, roasted or baked at a higher temperature. It is formed from the reaction of reducing sugars ...

An amperometric urea biosensor based on facilitated transfer of urease-generated ammonium ion by a neutral carrier (ionophore) dibenzo-18-crown-6 across the polarizable membrane-stabilized interface between water and ...

There are of least six reported s in Ethiopiil of a total of 65 species of Kniphofia in the world all of Vlhich are restricted to tropical Jifrica andYemen. Rniphofia foliosa (family Liliaceee) known in J\mharic as ...

In Ethiopiafaba bean and potato are two important crops for food security and nutrition. Root rot/wilt is a notorious fungal disease of faba bean caused by Fusarium spp., while late blight is a potato disease due to attack ...

An internationally known test method for nitrite was applied to determine the anion in tap and river water samples. The method is based on the reaction of nitrite with sulphanilamide in acidic medium to form diazonium ...

AC and DC voltammetry and flow injection amperometry methods were employed in this work. The influence of ionophores on the facilitated transfer of K+ and Na+ ions across membrane stabilized water/nitrobenzene interface ...
