One of them was the
aqueous solution inclusive 0.1 mol of urea and the second type was solution inclusive 0.1 mol of NaCl dissolved in the water.
In LiBr-[H.sub.2]O absorber application, due to the hydrophobicity of the membrane, the
aqueous solution cannot enter the membrane pores, while at the vapor side, the vapor enters the pore and a liquid-vapor interface is formed at the pore mouths on the solution side.
This study showed that a good adsorbent for the removal of Pb(II) from
aqueous solution can be obtained from activated carbon prepared from cow dung.
The aim of this research work is to create accurate data on thermodynamic and transport properties of
aqueous solutions of citric acid and to know more about solute--solvent interactions, and ion-solvent interactions.

Chromium adsorption was computed from the difference of the initial and the final concentration of the chromium in
aqueous solution using the following mathematical relationship:
The growth solution for shape control was prepared by mixing 20 mL of 50 mM CTAB
aqueous solution with 1 mL of 10 mM Pd[Cl.sub.4.sup.2-]
aqueous solution in a glass vial.

aqueous solutions using waste of tea factory: adsorption on a fixed-bed column'," Journal of Hazardous Materials, vol.
In order to produce such a powder, the amount of Sm-Fe-N powder was fixed and the concentration of the
aqueous solution of cobalt sulfate heptahydrate was changed from 0.025 mol/l to 0.100 mol/l.
The basic stock solution of surfactants was prepared by dissolving 0.01 M CTAB and 0.02 M sodium hydroxide in
aqueous solution. The gold complex solution (10 mM) was prepared by dissolving NaAu[Cl.sub.4] x 2[H.sub.2]O in 10 mL
aqueous solution.
Raw, iron oxide, and aluminum oxide impregnated carbon nanotubes (CNTs) were found to be effective adsorbents for the removal of Cr(VI) ions from
aqueous solution. The removal of Cr(VI) ions was strongly dependent on pH, contact time, adsorbent dosage, and initial concentration of the Cr(VI) ions.
Fluorescence spectra were excited at the 412 nm (ThT absorption spectrum maximum in
aqueous solution) and fluorescence excitation spectra were recorded at the 490 nm (ThT fluorescence spectrum maximum in
aqueous solution).
