Summary: The adsorption efficiency of Pb(II) and Cd(II) from aqueous solutions using m-phenylenediamine-modified Amberlite XAD-4 resin was investigated. The impact of various factors such as pH, adsorbent amount, initial metal concentration, eluent type and volume, and flow rate on the retention of the metal ions was studied through column studies. The optimal conditions for quantitative adsorption were found to be pH 5, 10 mg/L concentration, 30 minutes stirring time, 0.2 g adsorbent amount, and 2.5 mL/min flow rate. The sorption data fit well with both the Langmuir and Freundlich equations, and the resin showed high metal adsorption capacity and satisfactory recovery of Pb(II) and Cd(II).

Summary: This study focuses on the removal of Cu(II) from aqueous environments due to its potential risks to human health. A magnetic hybrid aerogel (mGO-TETA-MWCNT) was synthesized through self-assembly of magnetic graphene oxide (mGO) and multiwalled carbon-nanotubes (MWCNT) functionalized with triethylenetetramine (TETA) via hydrothermal reduction. The prepared adsorbent showed high adsorption capacity for Cu(II) removal and exhibited good selectivity in the presence of other interfering metal ions. The aerogel can be regenerated for multiple cycles and successfully applied for Cu(II) removal from different water sources.
