Selective Speciation of Ferric Iron by a New Heterocyclic Ligand
The synthesis and analytical applications of the new heterocyclic ligand are described. The complexation reaction of the ligand with some cations was studied in aqueous methanol at room temperature using the spectrophotometric method. Results revealed that only the absorption spectra of the Fe (III)–ligand complex show a high redshift of the absorption maximum in the aqueous methanol soluti...
متن کاملSpeciation of molybdenum in river water by size fractionation and catalytic determination.
A speciation scheme of trace molybdenum was proposed for river water based on size fractionation by filtration and ultrafiltration and the catalytic spectrophotometric determination of the reactive molybdenum concentration (CR). The total concentration (CT) of molybdenum was determined by the same method after acid decomposition to obtain the concentration (CT - CR) of unreactive molybdenum. Mo...
متن کاملSpeciation of heavy metals in coastal water of Qeshm Island in the Persian Gulf
Fuel storage tanks are one of the main sources of water pollution as well as loss of crude oil and oil products in refineries. In the process of utilization of these tanks, considerable amounts of hydrocarbons may find their way into the coastal water, which eventually lead to loss of valuable hydrocarbons. Oil type, climatic condition and characteristics of oil tanks are among the main variab...
متن کاملArsenic speciation in the River Zenne, Belgium.
Arsenic species have been assessed in the Zenne River, a sewage contaminated tributary of the Scheldt estuary, in winter 2003. The highest total dissolved As concentrations were found in the middle part of the river with values up to 3.6 microg L(-1). Particulate As concentrations increase towards the mouth of the River with highest levels of 2 microg L(-1). A very good correlation between the ...
متن کاملIron speciation in hypotransferrinaemic mouse serum.
A mouse model of human disease was recently described by Bemstein I1 I . Hypotransferrinaernic mice have 5O-fold decreased serum transfenin levels, hypochromic. riiicrocytic (iron deficient) anaemia but develop liver iron overload I1.21. These mice parallel for the rare human disease atrmsferrlnaemia 13.41 and may be a useful model for hiiman iron overload disorders. Great interest is currently...
