In this work, a nickel-modified glassy carbon electrode (GCE) was prepared using a potentiostatic method in 0.1 M acetate buffer solution at pH 4.0 containing 1.0 mM nickel nitrate. Nickel hydroxide nanoparticles were prepared using consecutive potential scanning in 0.1 M NaOH solution. The as-prepared catalyst was characterized by field emission scanning electron microscopy and electrochemical...

The microwave solvothermal reaction of nickel nitrate with trimesic acid provided the title compound, [Ni(3)(BTC)(2)(H(2)O)(12)](n) (BTC = benzene-1,3,5-tricarboxyl-ate anion, C(9)H(3)O(6)), which is a metal coordination polymer composed of one-dimensional zigzag chains. The crystal under investigation was ramecically twinned with an approximate twin domain ratio of 1:1. In the asymmetric unit,...

Today, soil pollution with heavy metals is a major environmental concern across the world. Phytoremediation is defined as a technique through which plants are able to absorb contaminants and potently recover the soil that is polluted by heavy metals. The present study aimed to investigate the level of nickel concentration in the roots, stems, and leaves of sunflower, as well as the mobility of ...

The reaction of nickel salts and 4,4'-bipyridine with 2,2'-bi-imidazole (H(2)biim) yielded the title complex, [Ni(C(6)H(6)N(4))(3)](NO(3))(2)·C(3)H(7)NO. The Ni(II) atom is chelated by three H(2)biim ligands in a distorted octa-hedral coordination geometry. The two nitrate anions and one dimethyl-formamide (DMF) mol-ecule are not coordinated. The compound has a three-dimensional structure, form...

A pot experiment was conducted based on a factorial study and complete random block design with three replicates to investigate the phytoremediation potential of Sorghum biocilor L. in soils polluted with nickel and manganese during 2017-2018. The first factor was nickel nitrate (0, 60, and 120 mg kg-1 soil) and the second factor comprised of manganese sulphate (0, 50, and 100 µM). The characte...

We report on a rapid, green, and cost-effective fabrication of nickel(-iron) oxyhydroxides by drop-coating reconstructing water-soluble nitrate precursors, their application for the OER oxidation 5-hydroxymethylfurfural (HMF).

Abstract Ammonium nitrate is a hygroscopic and caking product for growing agricultural products. In order to improve the properties of ammonium nitrate, composition calcined crushed cathode material from used lithium ion battery was studied. Since mainly consists lithium, cobalt, manganese nickel, it has been adopted as polymicroelement-containing additive nitrate. Studies have shown that intro...

A method for the determination of total selenium in wheat and wheat flour using graphite furnace atomic absorption spectrometry (GFAAS) with palladium/ascorbic acid as a chemical modifier was studied. The effects of nickel nitrate, palladium/ascorbic acid, and palladium/magnesium nitrate as chemical modifiers on the sensitivity in the determination of selenite, selenate and selenomethionine by ...
