Tuning phase compositions of MoS2 nanomaterials for enhanced heavy metal removal: performance and mechanism

“…12,18,[38][39][40] Such a high removal capacity highlights the MoS 2 's effectiveness in removing heavy metal ions with less affinity and selectivity to other nanomaterial adsorbents (e.g. Fe 2 O 3 , 41 Al 2 O 3 , 42,43 TiO 2 , 44,45 quantum dots, 26 nZVI 46 ). MoS 2 nanosheets revealed great performance for heavy metal remediation.…”

Superb adsorption capacity of biochar derived from leather shavings for Congo red

“…The usage of this waste may contribute to disposal management of disposal, which is in agreement with the “3R” principles, “reduce, reuse and recycle”. Second, metallic compounds show excellent adsorption capacity for CR, such as MgO/SiO 2 , 24 Al 2 O 3 , 25 CaCO 3 , 23 and ZnO-modified compounds. 10 Moreover, –NH 2 groups is typically present as a functional group in adsorbents for the adsorption of heavy metals.…”
