Bis( N,N '‐Disalicylalethylenediamine)‐μ ‐ Aquodicobalt(II)

Abstract

pered bottles to minimize atmospheric oxidation. The iodide is considerably less soluble in water than the bromide and both are sparingly soluble in liquid ammonia. Both salts are decomposed by bases and are converted to nickel(I1) hydroxide by boiling with water. Thermal dissociation of the hexamminenickel(I1) bromide yields successively compounds containing 2, 1, 0 mols of ammonia. The corresponding iodide is less stable and loses ammonia to form the diammine, and finally the unsolvated iodide.

Cloud Point Extraction Spectrophotometric Determination of Copper, Chromium and Cobalt by Salen as Reagent in Wastewater of Iraq

“…It is due to the yellowish orange colour of these components the band at 320 nm may be caused by electronic transition n → π* which belongs to C=N. For the transform at 264 nm may be caused by electronic transition of n → π* of double bond due to C=N and the aromatic ring 23,24 . The complex with Cu-Salen the maxima absorption at 361 was appeared at pH 8, 70 µg L -1 and 0.8 mL Triton X-100.…”

“…Then the modified GC electrode was introduced from one side of the cell. Also from the opposite, side a white light LED, as well as a digital camera (model: AGPtek, magnifying ratio: X 800) were positioned with angle between [10][11][12][13][14][15][16][17][18][19][20] o versus the GC carbon electrode. Also to remove the hysteresis of the GC electrode from any adsorption and diffusion of humidity, an IR light source was positioned next to the GC electrode to eliminate the memory effect.…”
