A novel monolith ZnS-ZIF-8 adsorption material for ultraeffective Hg (II) capture from wastewater

Thiosemicarbazone modified zeolitic imidazolate framework (TSC-ZIF) for mercury(ii) removal from water

“…S12 †), with a typical SOD structure. 68 N 2 sorption-desorption isotherm. The dinitrogen sorption isotherms of the Ald-ZIFs and TSC-ZIFs were measured at 77 K, and the Brunauer-Emmett-Teller (BET) and pore volume of all the samples were calculated (Table 2 and Fig.…”

“…The high sulfur content in the hybrid material exhibits outstanding adsorption of Hg(II), where the removal was achieved through simple ltration of contaminated water using the monolith ZnS-ZIF-8. 68 This study presents the preparation of a new class of aldehyde modied ZIF-8 derivatives (Ald-ZIF), which were further functionalized with thiosemicarbazone (TSC) groups for the removal of mercury(II) ions from water. These Ald-ZIF were prepared through the integration of mixed-linkers: 2-methylimidazole (MIM) and imidazole-4-carbaldehyde (AldIM).…”

Adsorption Processing for the Removal of Toxic Hg(II) from Liquid Effluents: Advances in the 2019 Year

“…A monolithic adsorption material (ZnS-ZIF-8) was prepared by means of the functionalized filter paper and it was used to Hg (II) capture from wastewater [60]. From a solution containing 0.2 g/L Hg(II), near quantitative adsorption was reached in the 2-7 pH range.…”

Adsorption and kinetic study of Cr(VI) on ZIF-8 based composites

“…Furthermore, fast adsorption and removal of benzotriazole by ZIF-8 was reported by Xiu-Ping Yan et al [32]. Similarly adsorption of various heavy metals such as antimony, arsenic, mercury and lead etc has also been studied extensively [33][34][35]. Furthermore, ZIF-8 has recently been demonstrated as highly efficient material for Cr(VI) removal, with partial reduction process [36].…”
