Two approaches are proposed for use of anion carriers. The first approach is development of an adsorbent specific to nitrite based on cobalt(III) complexes of 6-octadecyl-1, 4, 8, 11-tetraazacyclotetradecane-5, 7-dione impregnated in Amberlite XAD-7. The second one is spectrophotometric determination of fluoride followed by selective extraction with molybdenum(V) complex of tetraphenylporphyrin.
