Three organic phosphorous compounds containing bridge
with (PhO) phenoxide and (Ph) phenyl group, to be used as materials derived element
cadmium ion according to the (liquid - liquid) extraction method that apply to widely used
in the restoration
of metal ions operations starting from aqueous solutions in mining
operations to environmental applications, and identified some of the physical properties
(melting point, spectra UV, IR).
Photometric method was adopted to determine the concentrations, as it used the
solution of 2-Nitroso, 1- Naphthol to determine the concentrations of cadmium ion in the
aqueous phase after extraction and its concentrations in the organic phase based on the
difference between the concentrations of primitive prepared aqueous solution and the final
concentrations in the aqueous phase.
Distribution Ratio DCd was studied of the ion cadmium between the aqueous medium
of the acid solution of Sulfuric and central Organic Dilutions containing different
concentrations of the previous prepared organophosphorus compounds also was studied the
Distribution Ratio DCd of ion cadmium depending of changing of pH-values in aqueous
medium and central organic Includes fixed concentration from the previous prepared
organophosphorus compounds and registered the distribution of information focus
numerically and graphically.
