Evans N. Mainsah

Dear Sir, i suppose the best way is to get a solvent in which on is soluble and the other is not. For instance, solubility of zinc in water depends on temperature and pH, is your complex soluble in water? If yes, then use water as solvent to separate them

Singaravelan Ramakrishnan

The complex itself is insoluble in water

what is the nature of the complex? Crystalline? If yes, do the crystals look different from the zinc metal? Did you try other solvents? For now, I think solvent extraction is the best choice, so get a solvent that can dissolve one and leave the other
