This study provides an extensive dataset of dissolved trace metals (silver, cadmium, copper, nickel, lead, iron, and zinc), inorganic (ammonia, nitrate, phosphate and silicates), and organic (urea, dissolved organic nitrogen, carbon and phosphorous, as well as particulate carbon and nitrogen) constituents during high and low riverine flow conditions in surface waters of the Long Island Sound. A...

The title compound, [Ni(C(9)H(9)O(3))(2)], was synthesized by the reaction of 3-ethoxy-salicylaldehyde with nickel(II) nitrate in methanol solution. The asymmetric unit onsists of two half-molecules; each Ni atom lies on a centre of symmetry. The Ni(II) ions are coordinated by four O atoms from two deprotonated 3-ethoxy-salicylaldehyde ligands in a slightly distorted square-planar coordination ...

In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

The problems encountered in platform AAS determinations of selenium in biological fluids were recently reported by Carnrick et al. [1]. The presence of phosphates produces a spectral interference for the selenium determination at 196.0 nm, avoided by using Zeeman background correction. On the other hand, Hoenig and Van Hoeyweghen show that spectral interference of phosphates in animal tissues m...

The protection of metallic surface is commonly done with zinc phosphate in acid aqueous phosphate solutions containing zinc ions and phosphoric acid, as well in addition of other metallic ions (nickel, chromium, calcium, niobium etc.), in presence of accelerators as nitrate ions, hydroxylamine sulfate, benzotriazole and others. The present article is a study on the surface structure of zinc pho...
