Abstract
The inhibition of corrosion of iron in 2M nitric acid and 2M sulfuric acid solutions by substituted
phenylhydantoin, thiohydantoin, and dithiohydantoin compounds was measured using thermometric,
weight loss, and polarization methods. The three methods gave consistent results. The polarization
curves indicated that the hydantoin compounds act as mixed-type inhibitors. The adsorption of the
inhibitors were found to obey the Temkin adsorption isotherm. The higher inhibition efficiency of the
additives in nitric with respect to sulfuric acid solution may be attributed to the reduced formation of
soluble quaternary nitrogen salts in nitric acid medium, favouring adsorption of the parent additive on the
metal surface. The obtained results indicate that the corrosion rate of iron in both acids increases with
increasing temperature, both in absence and presence of the tested inhibitors. Kinetic-thermodynamic
model functions and Temkin isotherm data an compared and discussed. The synergistic effect of halide
anions on the inhibition efficiency of the hydantoin compounds was also investigated.

Thermodynamic behaviour of complex antimonite ore for

Abstract
This paper outlines the hydrometallurgical processing and the various possible approaches for the
recovery of metallic antimony from its antimonite sulphide ore by electrolysis. Thermodynamic
calculations have been made to find the optimum conditions for roasting and/or sulphate roasting of Wadi
Abu Quraiya antimonite ore. The antimonite ore (Sb2S3) is roasted directly without concentration and
large savings in reagent and chemical processes are expected. A suitable roasting temperature of 1200 K
for 4 hours has been determined. Metallic antimony is' cathodically electrodeposited with a high current
efficiency at current densities of 350 to 500 A/m(2) depending on the composition of leach liquor
solutions. The results of the electron microscopy investigation confirmed by metal value data in the ASTM
cards are in good agreement with the chemical analysis.

Abstract
The efficiency of chloro, dichloro, trichloro, bromo, and iodoacetic acids as inhibitors for acid corrosion of
in-on was studied using polarization technique. A significant retardation of the corrosion rate Is observed
in the inhibited HNO3 solution. The rate of corrosion depends on the nature of the inhibitor and its
concentration and on the temperature of the system. It was found that iodoacetic acid has a significant
inhibiting effect on the corrosion of the metal and protection efficiencies approaching 91% were
measured. The inhibitor shifts the free corrosion potential in the cathodic direction and polarizes both the
cathodic and anodic half reactions. It was found that the compounds under consideration are
chemisorbed on the iron sun-face according to the Frumkin isotherm. The Tafel slope is approximately
constant and independent of the concentration of the inhibitor, The thermodynamic parameters of
adsorption obtained reveal a strong interaction of these inhibitors on the iron surface.

Abstract
Corrosion inhibition by methoionine (MET), citrulline (CIT), alanine (AL), glycine (GLY) and hydroxyproline
(HPR) with respect to the dissolution of tungsten stainless steels in hydrochloric acid solution was studied
using potentiodynamic, Tafel extrapolation and polarization resistance methods. Polarization curves
indicated that the primary passivation potential (Epp) and the transpassive region shift towards more
positive potentials in presence of the studied amino acids, i.e. there is more passivation at wide potential
range in the presence of amino acid inhibitors. The corrosion parameters are dependent on the
percentage of tungsten in the alloy composition as well as the nature of the tested amino acids. The
intermetallic compound Fe3W2 may form a galvanic cell with the matrix around the Fe3W2 phase within
the matrix that is formed as a dispersed phase.

Abstract
A study has been made to investigate the effect of some azoheterocyclic dyes of the type 3-arylazo 1,2,4-
triazole (AT) on the corrosion of copper exposed to 0.5 M nitric acid solution at different temperatures and
at different AT concentrations. Using potentiodynamic polarization and Tafel electrochemical methods, it
can be shown that AT compounds are good inhibitors of copper corrosion in HNO3 solution. The kinetic
and thermodynamic parameters of the inhibited system were determined. The high inhibition efficiency of
these compounds may be due to the adsorption of the additive itself and/or the adsorption of the formed
Cu(II)-AT complexes at the polarized electrode interface. Cathodic polarization measurements showed
that AT dyes are predominantly cationic inhibitors.

MATERIALS SCIENCE, MULTIDISCIPLINARY Q4
Abstract
The dissolution of aluminium in hydrochloric acid and sodium hydroxide solutions in the presence of
semicarbazide, thiosemicarbazide and sym.diphenylcarbazide as corrosion inhibitors has been studied
using thermometric, weight-loss and polarization methods. The three methods gave consistent results.
The higher inhibition efficiency of these compounds in acidic than in alkaline madia may be due to the
less negative potential of aluminium in hydrochloric acid solution, favouring adsorption of the additive.
The adsorption of these compounds were found to obey Frumkin adsorption isotherm.
Cathodic polarization measurements showed that these compounds are cathodic inhibitors and their
adsorption in the double layer does not change the mechanism of the hydrogen evolution reaction. The
results are analysed in terms of both molecular and cationic adsorption.

Inhibiting action of semicarbazide, thiosemicarbazide, sym. diphenylcarbazide towards corrosion of zinc
in hydrochloric acid has been investigated. The rate of corrosion depends on the nature of the inhibitor
and its concentration. The values of inhibition efficiency from, weight loss, thermometric measurements
are in good agreement with those obtained from polarization studies. From the polarization studies, the
inhibitors used act as mixed adsorption type inhibitors, increased adsorption resulting from an increase in
the electron density at the reactive C=S and C=O groups and N-atoms. The thermodynamic parameters
of adsorption obtained using Bockris-Swinkels adsorption isotherm reveal a strong interaction of these
carbazides on zinc surface.

Abstract
2,2'-Biimidazole complexes of MoO2(+2), MoO2+ and UO2(+2) have been prepared and characterized by
elemental analysis, conductance; and H-1 NMR, IR and electronic spectra. Two types of complexes have
been identified. Those obtained from slightly acidic solutions have the formulae MoO2(H2bim)Cl2.2H2O
1, UO2(H2bim)(Ac)2 2 and UO2(H2bim)Cl2.2H2O 3; whereas those from alkaline solutions have the
formulae Mo2O4(Hbim)2.2H2O 4, and MO2(Hbim)2 (M = Mo(VI) 5, U(VI) 6). The infrared spectra of these
complexes show characteristic biimidazole frequencies in the 3200-2500, 1550-1000 and 750 cm-1
regions as well as metal oxygen double bonds in the 900 cm-1 region. The stoichiometries of the acetate
complex has been confirmed from H-1 NMR signal ratios of biimidazole to acetate protons at 7.3 and 2.3
ppm, respectively. The electronic spectrum of molybdenum(V) complex showed d-d transition band at

22
congruent-to 13,500 cm-1 in accord with that reported for copper (d9) imidazole complexes; as well as
peaks due to charge transfer bands at 30,000-26,000 cm-1. Peaks assignable to BIM --> U(VI) were
located at congruent-to 26,600 cm-1. The most probable structures of these complexes have been
suggested.
