Question

Nickel can also form complexes with 1,10-phenanthroline. If you want to use the UV-vis spectrophotometric method to analyze iron in a sample that also contains nickel, think of a simple method that will allow you to overcome the heavy metal ion interference using several standard solutions.

Answer 1

Mond's process is very useful to separate Nickel from any metal mixture. In mond's process, Nickel react with carbon monoxide and from volatile Nickel tetracarbonyl Ni(CO)4.This compound is volatile so Ni(CO)4 can be easily seperated by Simple Evaporation. Then Ni can be extracted from Ni(CO)4 by thermal decomposition reaction. Thus nickel can be separated from any metal mixture
