Studied are the conditions for express determination of microamounts of iron with 4,7-diphenyl-1,10-phenanthroline (bathophenanthroline) in the form of ionic associate (IA) with NO3_ ions. A technique is proposed for pumping sorption of the IA from the solution by means of polyurethane foam. The sta...
