13/10/2020, · An efficient use of GPs/AAMs in real ,wastewater treatment, practices including economic evaluation is little investigated. Above all, these adsorbents show rather low selectivity, and therefore the ubiquitous metal ions (Na + , Ca 2+ , Mg 2+ , Fe 3+ ) present in ,wastewater, solutions demonstrate either competing interaction with the target ions, or the interaction has not been studied [ 57 ].
