Synergistic immobilization of UO22+ by novel graphitic carbon nitride @ layered double hydroxide nanocomposites from wastewater

Self-assembly of 2D-metal–organic framework/graphene oxide membranes as highly efficient adsorbents for the removal of Cs+ from aqueous solutions

“…For GO, the removal of Cs + become close to saturation within 150 min, and the growing tendency slows down with the increasing of contact time. To extract the interaction mechanism in details, the sorption kinetics is tted by the pseudo-rst-order model and pseudo-second-order model, 32 which are described as follows:…”

Recent Advances in Composites of Graphene and Layered Double Hydroxides for Water Remediation: A Review

“…In the solvothermal reaction,d eionized water is replaced by nonaqueous solvents to dissolve the precursor salts. [39,61] Furthermore, microwave irradiation,asas ubstitute for an autoclave, can effectivelys horten the synthesis time of G@LDH materials compared with traditional methods. [62,63] Lonkar et al synthesized aG /ZnAl-LDH composite by using the microwave method (Scheme2C).…”

“…[35][36][37] Compounds with uniform morphology and excellent crystallinity can be obtained by using the hydrothermal method. [38][39][40] Typically,amixed solution is used that contains precursor salts (nitrates, chlorides, sulfates,o rh ydroxides), urea, and graphene. After homogeneous mixing, the as-prepared suspension is transferred into a Te flon-lined stainless-steel autoclavea nd heateda tt he desired temperature for an extended period of time.…”
