Abstract
The current research study focusses on the recovery and reuse of Nickel chloride obtained from Ni-(DMG)2complex prepared during an undergraduate chemistry practical course. The complex was decomposed by using different acids followed by cooling at room temperature and refrigeration. Nickel (II) in the form of Nickel chloride, Nickel sulphate and Nickel nitrate was obtained after the acid digestion process. The recovered Ni(II) solution obtained was further reused for Ni (DMG)2 complex preparation The recovery and reuse technique are an attempt towards reducing the environmental footprint in an undergraduate chemistry laboratory and towards sustainable laboratory management.
