    2018-10-23 · Iron. Iron is the most important metal in heavy industries, Iron is the fourth most abundant element in earth’s crust after oxygen, silicon and aluminum as it forms (5.1 %) of the mass of the earth’s crust and this mass increases gradually as we come close to the center of earth, Iron

  • A New Method for Synthesis of Iron Phthalocyanine

    Iron phthalocyanine was prepared by the reaction of phthalic anhydride, urea and ferrous chloride by means of the solvent method with dioctyl phthalate as solvent, ammonium molybdenate as a catalyst and ammonium chloride as promoter. The reaction was carried out in the conditions that 2 hours was required for the first stage at the temperature of ca. 403 K and 6 hours was required for the

  • A new spectrophotometric method for the

    A critical experimental comparison between the Muir spectrophotometric method, the Kolthoff titrametric method and the new proposed method is presented. Whenever Fe(III) accounts for more than 50% of the total iron in a sample, the method of Muir overestimates Fe(II). The proposed method has a range of 1–10 μg ferrous iron.
