INJURY to the cornea with an iron-containing foreign body usually leaves a rust ring. Most surgeons advise complete removal of any rust, but this often causes considerable trauma to the already injured cornea. Desferrioxamine ("Desferal", Ciba Laboratories) is an iron-free compound isolated from a strain of Streptomycespilosus, which binds ferric ions to form an octahedral complex ferrioxamine....

Experimental investigations were undertaken in batch kinetic systems, for the removal of iron (II) from aqueous solutions using activated dolomite. The effect of the extent dolomite activation on the dissolution of magnesium and calcium from the dolomite lattice was determined. Under optimum experimental conditions there was a direct linear relationship between magnesium dissolution and iron (I...

Electrocoagulation (EC) is electrochemical water and wastewater treatment technology which in its simplest form uses an electrochemical cell where a dc voltage is applied to the electrodes, usually made of Iron or Aluminum, and the electrolyte is the water or wastewater. Current theory of EC has not been able to explain all the phenomena associated with the process, among others the differences...

Removal of iron from biologically important ligands by desferrioxamine (DF), in vitro, is exceedingly slow because of a kinetic barrier. This kinetic barrier can be overcome by a variety of a small molecular weight anions, of which nitrilotriacetate (NTA) is a prototype. We explored the effect of NTA on DF iron mobilization in vivo. Iron mobilization was increased and the effect was synergistic.

Aqueous contaminant removal in the presence of metallic iron (e.g. in Fe(0)/H(2)O systems) is characterized by the large diversity of removing agents. This paper analyses the synergistic effect of adsorption, co-precipitation and reduction on the process contaminant removal in Fe(0)/H(2)O systems on the basis of simple theoretical calculations. The system evolution is characterized by the perce...

Microbial reduction of perchlorate in the presence of zero-valent iron was examined in both batch and column reactors to assess the potential of iron as the electron donor for biological perchlorate reduction process. Iron-supported mixed cultures completely removed 65 mg/L of perchlorate in batch reactors in 8 days. The removal rate was similar to that observed with hydrogen gas (5%) and aceta...

The problems related to groundwater contamination by Iron and Fluoride are common and serious all over the world, especially in developing countries. Excess amounts of these contaminants have created health problems. For this reason, the maximum permissible limit for iron given by WHO and BIS is 1 mg/l, however 0.3 mg/l is the desirable limit. For fluoride, the maximum permissible limit is 1.5 ...

Waterborne viruses account for 30% to 40% of infectious diarrhea, and some could persevere months in nature move up 100 m groundwater. Using filtration setups, coagulation lessen virus charges as an efficient pre-treatment reducing viruses. This work discusses the present-day studies on mitigation using its three versions i.e., chemical (CC), enhanced coagulation, electrocoagulation (EC), debat...
