The separation of zinc(II) and cadmium(II) by liquid ...

Zn(II) is extracted as Zn(PMBP) 2 ·B2EHSO/TBP/TOPO. On the other hand, Cd(II) is found to be not extracted with these mixedligand systems under the experimental conditions. These results also demonstrate the mutual separation of Zn(II) and Cd(II) using the synergistic extraction with HPMBP in the presence of various neutral oxodonors.

Copper Chemistry

Copper Oxides Copper(I) oxides are more stable than the copper(II) oxides at high temperatures. Copper(I) oxide occurs native as the red cuprite. In the laboratory, the reduction of Fehling's solution with a reducing sugar such as glucose produces a red precipitate. The test is sensitive enough for even 1 mg of sugar to produce the ...
