The manner null which concentrates the cobalt complex salt from the cobalt complex salt content aqueous solution

摘要

PURPOSE: To directly concentrate the cobalt complex aqueous solution in an easy operation at a low energy cost in a short reaction time in the propanol- reutilizable state by adding propanol to an ammonium aqueous solution containing the cobalt complex. ;CONSTITUTION: A specific volume of propanol is added to an ammonia aqueous solution containing a cobalt complex at the ordinary temperature with stirring, and the mixture is allowed to stand. Thus, the mixture is separated into two phases consisting of an aqueous phase containing the cobalt complex and an aqueous phase containing the propanol, and the cobalt complex is concentrated because the volume of the aqueous phase containing the cobalt complex is extremely reduced.;COPYRIGHT: (C)1993,JPO&Japio
