Abstract

The preparation of 1-nitroso-2-naphthol and diethylammonium diethyldithiocarbamate foams is described. The effect of pH, plasticizer and shaking time on the collection efficiency of cobalt(II) on these reagent foams has been investigated. The collection of various concentrations of cobalt(II) on the proposed reagent foams packed in columns is quantitative at flow-rates of 5-6 ml cm-2 min-1.
