zinc ions are present in different types of industrial effluents, being responsible for environmental pollution. biosorption is a process in which solids of natural origin are employed for binding heavy metals. it is a promising alternative method to treat heavy metal wastes mainly because of high metal binding capacity. the effect of some important parameters on sorption capacity of cyanobacte...

Pilocarpine is a natural substance with potential application in the treatment of several diseases. In this work Fourier Transform (FT)-Raman spectrum and the Fourier Transform infra red (FT-IR) spectrum of pilocarpine hydrochloride C11H17N2O2 .Cl − were investigated at 300 K. Vibrational wavenumber and wave vector have been predicted using density functional theory (B3LYP) calculations with th...

Three experiments demonstrate that infra-red spectroscopic measures of bone mineral crystallinity are partially dependent upon sample preparation methods. Intensive grinding of bone samples for Fourier transform infra-red (FTIR) spectroscopic analysis results in a net decrease in splitting factor (SF), a common measure of apatite crystallinity. If grinding is overly intensive, SF measurement ma...

Fourier transform infra red (FTIR) and energy band gap of potassium lithium borate glasses of different composition have been studied using Fourier FTIR and UV-VIS spectroscopy techniques. The glasses were melted in the alumina crucible in an electric furnace at 1100°C for 30 min until homogenous melt was obtained. The X-ray diffraction analysis was adopted for confirming the amorphous nature o...

tio2/zro2 nanocomposite was obtained by the sonochemical technique. in this method, two separate gels containing zirconium and titanium were prepared and mixed together. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4. the precursor titanium tetra isopropoxide (ttip) dissolved in isopropanol. mixing of titanium and zirconium gels was resulted in a yellow tio2/zro2 ...

In the present paper, we have studied immunglobulin (IgG) of epileptic children, migraineous and paralytic patients.  We have compared our results with normal healthy controls. We found that the bands ranges from 1151.94 to 1168.28 cm-1 due to phospholipids (P-O-C ) group appear in some of the migraineous and paralytic patients only. These bands are absent in normal and epileptic patients. The ...

aim: to enhance the aqueous solubility of olanzapine by using the solid dispersion technique. solid dispersions of olanzapine were prepared by the dispersion method using using pgs and ssg as carriers. drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...
