Under optimized conditions, the material was utilized in preconcentration experiments, which culminated in an enrichment factor of 41.3-fold.With the aid of the enrichment factor, experiments were carried out to determine the Cu(II) content in tap water and natural water. Pre-concentration method was also applied to a certified reference material (1643e) and the concentration found was 23.03 ± 0.79 g L−1, whereas the specified Cu(II) concentration was 22.7 ± 0.31 g L−1.
