Closed-loop recirculating manifold for matrix isolation in flow injection flame atomic absorption spectrometry. Analysis of silver electrolysis solutions

Abstract
Two flow injection procedures have been investigated for the determination of some elements
in silver electrolysis solutions, for which the problem of the formation of silver acetylide needs to be
addressed. A single line manifold was found to give acceptable results for limited time periods, but for
prolonged operation it was necessary to remove the silver. This was achieved with a recirculating reactor
in which the silver was precipitated as the chloride and retained on a filter of nylon fibers. Good recoveries
of copper, iron, nickel and zinc from solutions containing up to 100 g/1. silver were obtained with over
95% of the silver retained on the filter. The filter was regenerated rapidly by flushing with ammonia
solution.
