In order to study the kinetic behavior of ligand binding, flash photolysis is widely used with various hemoproteins [l-4]. The applicability of this method, however, seems to be limited to the ferrous ligated complexes, such as CO, O2 and NO complexes, since it has been believed that only those ferrous complexes are photodissociable. To extend this technique to the ferric state, we have examine...

Introduction: The objective of this study was to investigate wastewater quality and the efficiency of removal of wastewater contaminants produced by a tile factory by using ferric chloride, ferrous sulfate, ferric sulfate, aluminum sulfate (alum) and poly-aluminum chloride (PAC) coagulants. Materials and Methods: This is an applied study. A composite sample was taken of the wastewater producti...

A rapid technique for the determination of iron in serum, after the intravenous injection of iron-dextran, is presented. Dithionite is used for the reduction of ferric to ferrous iron. The use of a detergent solution enables protein precipitation to be omitted. The iron reagent, 4: 7-diphenyl-1: 10-phenanthroline, and its ferrous complex are both soluble in the dilute detergent solution. Lipaem...

Cadmium plating for Eaton Corporation began very early, with the first production baths being the "Udylite" process, then the first proprietary process that was introduced in the 1920's. Cadmium plating was widely used throughout the electrical components part of the business as It was a relatively simple process that could be plated on ferrous and non-ferrous parts. For high current and relati...

The treatment of Wastes Electrical and Electronic Equipment (WEEE) is a significant source secondary raw materials. Ferrous non-ferrous metals, electronic equipment, plastics are among these One the most common metals sourced out WEEE stainless steel. Dishwashers sources steel, so large amounts steel can be recovered from them. In this project, dishwashers were submitted to size reduction via s...

The aim of this study was to develop a method for the preparation of ferrous fumarate and folic acid oral dispersible tablets and their quality evaluation through HPLC and spectrophotometry. The formulation was optimized with dissolubility and dispersed uniformity as reference parameters by singlefactor and orthogonal experiments. The results exhibited that the optimal formulation contained: 18...

Persulfides of cysteine (CysSSH), glutathione (GSSH) or N-methoxycarbonyl-penicillamine (NAcPenSSH) react with the ferric form of myoglobin (metMb(iii)) to yield the oxy-ferrous (oxyMb(ii)) or deoxy-ferrous (deoxyMb(ii)) forms of myoglobin under aerobic or anaerobic conditions, respectively. Under aerobic conditions, CysSSH and NAcPenSSH react with the hypervalent form of myoglobin (ferrylMb(iv...

Properties ofa heat-labile glucose transport system in Thiobacillusferrooxidans strain AP-44 were investigated with iron-grown cells. [14C]glucose was incorporated into ceil fractions, and the cells metabolized [14C]glucose to 14CO2. Amytal, rotenone, cyanide, azide, 2,4-dinitrophenol, and dicyclohexylcarbodiimide strongly inhibited [14C]glucose uptake activity, suggesting the presence of an en...

Two environmentally safe iron compounds (synthetic magnetite and ferrous gluconate) have been evaluated as sulphide scavengers at temperature conditions of 25 °C, 35 °C, 45 °C and 55 °C at pH of 12 in a sulphide-contaminated drilling mud. The ferrous complex was found to be a better scavenger than synthetic magnetite. It exhibited 100 % scavenging efficiency within the first 40 minutes of agita...

A simple and accurate model is presented for computation of the electromagnetic induction (EMI) resonant frequencies of canonical conducting and ferrous targets, in particular, finite-length cylinders and rings. The imaginary resonant frequencies correspond to the well known exponential decay constants of interest for time-domain EMI interaction with conducting and ferrous targets. The results ...
