This indicator is colorless in acidic … WebApr 13, 2024 · As can be observed, the Cu(II) adsorption was extremely pH-dependent. At low pH values (pH 1 and 2), the adsorption capacity values were almost zero, which can be related to the excess of H + ions. These hydrogen ions can compete with the Cu 2+ ions for the surface active sites, leading to their blockage (Kim et al. 2016). Consequently, low ...
