Actuated by the non-ionic heavy metal of antimony (Sb) contaminants with undesired toxicity to the environment and human health, capturing Sb is urgent to remedy contaminated water. Herein, the lamellar MnCo hydrotalcite was grown on catkin-derived biochar through the in situ etching of ZIF-L to construct a hierarchical microtube@nanosheet hybrid (CLMH) for Sb immobilization. The adsorption behaviour and mechanism of trivalent antimony (Sb (III)) on the CLMH were investigated.

- * The study highlights a novel approach to the secondary application of the recovered mercury-loaded adsorbent, UiO-66-S-Hg, as an efficient catalyst for producing vinyl benzoates.
- * Results indicate that this method not only helps treat mercury contamination but also mitigates potential secondary pollution and promotes the resource utilization of immobilized mercury.
Article Synopsis
- - A zirconium-porphyrin based organic framework, PCN-222, was tested for its ability to adsorb Sb(III) from water, showing rapid adsorption and high capacity.
- - The adsorption performance of PCN-222 is influenced by pH, with greater efficiency at pH levels of 2 and 8 compared to pH 5, due to different interactions with antimony based on pH.
- - The framework's design allows for effective regeneration after use, making PCN-222 a promising material for water treatment applications to remove Sb(III).
The application of antimony containing compounds in the industry has generated considerable antimony contaminants, which requires to develop methods that are as efficient as possible to remove antimony from water in the view of human health. The adsorption is among the most high-efficiency and reliable purification methods for hazardous materials due to the simple operation, convenient recycling and low cost. Herein, this review systematically summarizes the functional materials that are used to adsorb antimony from water, including metal (oxides) based materials, carbon-based materials, MOFs and molecular sieves, layered double hydroxides, natural materials, and organic-inorganic hybrids.
