An apparatus for separating impurities from a liquid by a non-dispersive contacting of a liquid&#x2014;liquid reactive systems, the liquids being immiscible with each other, having a cylindrical column separated into a first stage and a second stage, a plurality of modules of packed metallic fibers mounted in the first stage of the column on a support, a first distributor provided in the first stage of the column for distributing a first liquid located above the support such that the first liquid completely wets the fibers by capillary action and forms a film thereon, a second distributor fitted at a bottom portion of the second stage for distributing a second liquid containing impurities on to the metallic fibers, wherein the second liquid flows concurrently with said first liquid so that the impurities present in the second liquid react with the first liquid and dissolve therein and a separator connected to a bottom of said column separates the first liquid and purified second liquid.
