| چکیده | ||
| Cyclohexylidine-ammonium-2-aminocyclohexyline-l-cyclohexee-l- dithiocarboxylate (CCCD) is employed for the gravimetric determination of Ni (II). In neutral or ammoniacal solutions, the metal forms a violet precipitate with the reagent which can be weighed as Ni (C13H18NS2)a2f ter drying at 115 - 120?C Using this procedure, the nickel content of steel samples can also be determined accurately. The purity of the precipitate and complete removal of interferences are confirmed by differential pulse polarography | ||
