Sorption extraction of Cu (II) and Co (II) by modified composite based on nanoporous aluminum oxide

The application of modified nanoporous aluminum oxide (PAO) as a composite for concentration and extraction of heavy metals is discussed in the article. There are identified the conditions for the synthesis of PAO matrix, selected the optimum surface-active agent for its modification. Spectrophotometric investigations have shown that the synthesized sorbent has complexing properties and it is suitable for concentration of metals from solutions.
