Adsorption potential of lead(II) ions from aqueous solutions onto Capsicum annuum seeds
(Taylor & Francis Inc, 2007)
The purpose of this work was to evaluate the adsorption potential of Capsicum annumn seeds, in a batch system for the removal of lead(H) ions from aqueous solutions. The experimental results showed that this agricultural ...
Electrochemical copolymerization of aniline and anilinesulfonic acids in FSO3H/acetonitrile solution
(John Wiley & Sons Inc, 2002)
The effects of 2-aminobenzenesulfonic acid (orthanilic acid), 3-aminobenzenesulfonic acid (metanilic acid), and 4-aminobenzenesulfonic acid (sulfanilic acid) on the electropreparation and properties of polyaniline (PANI) ...
Validated method for the determination of deflazacort by a flow-injection analysis with UV detection: Application to pharmaceutical formulations
(Taylor & Francis Inc, 2004)
A simple, precise, accurate, and fast flow-injection analysis (FIA) method employing UV detection is described for the determination of deflazacort (DEF) in pharmaceutical tablets. The best carrier solvent system consisted ...
Space-time algebra for the generalization of gravitational field equations
(Indian Acad Sciences, 2013)
The Maxwell-Proca-like field equations of gravitolectromagnetism are formulated using space-time algebra (STA). The gravitational wave equation with massive gravitons and gravitomagnetic monopoles has been derived in terms ...
Pseudospin Symmetry in Trigonometric Poschl-Teller Potential
(World Scientific Publ Co Pte LTD, 2012)
We investigated the analytical (s) over bar -wave solutions of Dirac equation for trigonometric Poschl-Teller (PT) potential under the pseudospin symmetry condition. The energy eigenvalues equation and corresponding wave ...
FT-IR spectroscopic study on some Hofmann-T-d type complexes: Ni(4-Phenylpyridine)(2)M(CN)(4) (M = Cd or Hg)
(Walter De Gruyter GMBH, 2005)
New Hofmann-T-d type complexes in the form of Ni(4-Phenylpyridine)(2)M(CN)(4) (M = Cd or Hg) were prepared in powder form and their infrared spectra are reported in the region of 4000200 cm(-1). From the spectral findings, ...
Gauge transformation and electromagnetism with biquaternions
(Edp Sciences S A, 2006)
After de. ning biquaternions with complex numbers, the algebra of biquaternions and some properties are introduced. Maxwell's equations without sources in the dimensionless form are given. Then Maxwell's equations are ...
Structural stabilities of water-soluble MnTDCSPP, MnTSPP, and supported analogues toward hydrogen peroxide and sodium hypochlorite
(Wiley-Blackwell, 2000)
This article describes the structural stabilities of 5,10,15,20-tetrakis(2.6-dichloro-3-sulfonatophenyl)porphinatomanganese(III) X (X: OH-. H2O) (MnTDCSPP), 5,10,15,20-tetra(4-sulfonatophenyl)porphinatomanganese(III) X (X: ...
Determination of the equilibrium, kinetic and thermodynamic parameters of adsorption of copper(II) ions onto seeds of Capsicum annuum
(Elsevier Science BV, 2005)
Adsorption of copper ions onto Capsicum annuum (red pepper) seeds was investigated with the variation in the parameters of pH, contact time, adsorbent and copper(II) concentrations and temperature. The nature of the possible ...
Spectroscopic determination of acid dissociation constants of some pyridyl Shiff bases
(American Chemical Society, 2006)
The acid dissociation constants (pK(a)) of eight biologically active pyridyl Shiff bases were determined using a UV-vis spectroscopic technique at 25 +/- 0.1 degrees C. The first acidity constants (pK(a1)) of the ...
