This paper describes the Spectrophotometric and titrimetric methods for the determination of gentamycin and amoxycillin. The use of potassium iodate reagent for direct titrimetric method for the determination of some selected antibiotic has been described. The end point was characterized by a sharp change in color from colorless to deep red followed by spectrophotometric measurements.

Background and Objectives: Measurement of light intensity is a recommended practice for insuring the delivery of required germicidal dose in disinfection operations by UV lamps. Use of sensitive to light chemicals which is the base of actionometeric methods could be considered as a suitable manner for estimating the intensity of UV lamp in circumstances that special radiometers are not availabl...

Systematic explorations of new phases in the Ag(I)-Ti(IV)/V(V)/Mo(VI)-iodate systems led to four new quaternary silver iodates, namely, Ag(2)Ti(IO(3))(6), Ag(2)(VO(2))(IO(3))(3), Ag(2)(V(2)O(4))(IO(3))(4), and Ag(2)(MoO(2))(IO(3))(4). They represent the first examples of silver iodates containing d(0) transition metal cations. Ag(2)Ti(IO(3))(6) is isostructural with K(2)Ti(IO(3))(6) and its str...

PURPOSE To test the hypothesis that dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) provides a useful in vivo measure of passive blood retinal barrier permeability surface area product (BRB PS) in experimental diabetic retinopathy. METHODS BRB PS (cm(3)/min) was measured using DCE-MRI and Gd-DTPA (MW 590 Da) in urethane-anesthetized control rats, sodium iodate-treated rats, rat...

Iodine is an important element in studies of environmental protection and human health, global-scale hydrologic processes and nuclear nonproliferation. Biogeochemical cycling of iodine is complex, because iodine occurs in multiple oxidation states and as inorganic and organic species that may be hydrophilic, atmophilic, and biophilic. In this study, we applied new analytical techniques to study...

BACKGROUND Fenton reaction (Fe2++H2O2→Fe3++•OH+OH-) is of special significance in the thyroid gland, as both its substrates, i.e. H2O2 and Fe2+, are required for thyroid hormone synthesis. Also iodine, an essential element supplied by the diet, is indispensable for thyroid hormone synthesis. It is well known that iodine affects red-ox balance. One of the most frequently examined oxidative proce...

In the present investigation, lead iodate crystals were grown in silica gel at ambient temperature. The effect of various parameters like gel concentration, pH of gel, gel ageing, concentration of the reactants on the growth of these crystals were studied. Good quality crystals having different morphologies and habits were obtained. Some of These crystals were opaque and some were translucent.
