Abstract:
In this papetr the optimum conditIoas for 6 Br-PADAP-Ni complex formation have been studied. The interference of other elements can be elimenated by extraction of the complex with tri-octylam9ae-dimethyl benzene from 7-8 N hydrochloric acid. The sensitivity of this extractant is abont ten times than that with ethyl ether.
