In this research complexation of dioxovanadium(V) with nitrilotriacetic acid (NTA) at differentionic strengths (0.1 to 1.0 mol dm-3) of sodium perchlorate as supporting electrolyte and pH rangeof 1.00-2.50 at 25 °C has been investigated by a combination of potentiometric and UVspectrophotometric measurements. Stability constants of two species, V0211L- and VO2H2L havebeen calculated. Ionic stre...

High concentrations of ammonium in drinking water can cause many diseases and environmental problems such as eutrophication. Therefore, high-performance and eco-friendly methods for purification are of great importance and must be considered. Recently, bioelectrochemical systems have been successfully applied for the removal of many pollutants from water and wastewater. In the present work, amm...

An efficient and convenient synthesis of novel tetrahydrobenzo[c]acridin-8(7H)-one derivatives is described using the electrogenerated anion of acetonitriles as the base in the presence of tetrabutylammonium fluoride as an effective supporting electrolyte in a one-pot, three-component condensation of aromatic aldehyde, dimedone and 1-naphthyl amine. The reaction is carried out in an undivided c...

A scheme to model the dependence of a solute redox potential on the supporting electrolyte is proposed, and the results are compared to experimental observations and other reported theoretical models. An improved agreement with experiment is exhibited if the effect of the supporting electrolyte on the redox potential is modeled through a concentration change induced via ion pair formation with ...

Water and nitrogen are two of the most important factors for plant growth and development. However, little is known about effects of N on water translocation between connected bamboo ramets. We performed experiment connected Indocalamus decorus ramets in adjacent pots with different soil water contents and three N levels. We determined antioxidase activities, concentration of osmotic adjustment...

The influences of the potential, the concentration and the nature of the supporting electrolyte on the rate of the reduction of nitrate on tin were tudied by both voltammetry and constant potential electrolytic experiments. Both the rate of the reduction of nitrate and the yield of nitrogen increase as the negative potential increases from−1.8 to−2.8 V versus Ag/AgCl, hile the yield of nitrite ...

the voltammetric characteristics of mo (vi) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-bap) and piperidinium perchlorate (pp) + piperidine (p) as  two different types supporting electrolytes, have been studied in chloroform. with the both supporting electrolytes a two electron irreversible process for the reduction  of mo (vi) oxinate was observed. p...

Graphite oxide was synthesized from natural flake graphite by the modified Hummers method. In brief, 200 mg of Graphite particles were immersed in Concentrated sulfuric acid (46 ml) and KMnO4 (6 g) was added slowly in small quantities in which temperature was maintained between the 0 and 5 c using an ice bath, after the complete oxidation of KMnO4, the mixture was heated to 37 c and kept at thi...
