The efficient adsorption of heavy metal ions from wastewater has become a serious challenge from both environmental and biological viewpoints. Recently, porous metal‐organic frameworks (MOFs), with metallic clusters and organic linkers, have been developed as promising structures in the capture of different toxic and hazardous substances, including heavy metal ions, because of their unique features. Here there is a collection for recent progress in the field of water remediation from the variable‐valent metals in polluted water and the corresponding MOFs which are able to remove these pollutant agents from water. Meanwhile, effective factors in the absorption of metal ions are discussed. MOFs are considered to be a promising candidate for metal ions removal from wastewater.

Mercury is a toxic metal, thus, it is an element which has more and more restrictions in its uses, but despite the above, the removal of this metal, from whatever the form in which it is encountered (zero valent metal, inorganic, or organic compounds), and from different sources, is of a widespread interest. In the case of Hg(II), or Hg2+, the investigations about the treatment of Hg(II)-bearing liquid effluents (real or in most cases synthetic solutions) appear not to end, and from the various separation technologies, adsorption is the most popular among researchers. In this topic, and in the 2019 year, more than 100 publications had been devoted to this field: Hg(II)-removal-adsorption. This work examined all of them.

“…In previous studies, a variety of adsorbents have been used to remove Cu(II) from aqueous solutions, mainly including inorganic adsorbents, organic synthetic adsorbents and natural modified adsorbents . However, the existing adsorbent materials are usually difficult to prepare owing to the complex and expensive preparation process required, and some of them are likely to cause a waste disposal problem after the water treatment process . Meanwhile, we have long since lost sight of the adaptability of adsorbent materials to randomly changeable water environments in real applications; for example, the pollutant concentrations in water will vary randomly from mixtures of different emissions, and the water temperatures will also vary with different weather conditions, all of which require highly adaptable materials .…”

BACKGROUND: Cu(II)-containing wastewater causes serious pollution of the water environment. Adsorption is one of the most commonly used water purification methods, with the selection of suitable adsorbents being the key factor. This motivates the development of new efficient adsorbents to purify Cu(II)-containing wastewater. RESULTS:A highly adaptable polyanionic gel (PAG) was synthesized by the facile crosslinking copolymerization of acrylic acid (AA) and triallylmethylammonium chloride (TAMAC) at 65 ∘ C for 0.5 h, followed by a simple neutralization treatment, avoiding the inconvenience of the complex and expensive preparation process required to prepare existing adsorbents. When first used as an adsorbent material, PAG achieved highly efficient purification of a wide concentration range of 10-2000 mg L −1 Cu(II)-containing wastewater. The PAG adsorption capacity for Cu(II) was 222.2 mg g −1 , which was higher than the values of selected existing adsorbent materials (9.50-214 mg g −1 ), and PAG had the advantages of being eco-friendly, facilely obtained and regenerable. Also, PAG maintained stable adsorption ability even when the adsorption temperature varied from 30 to 50 ∘ C. Moreover, a series of new adsorption effects were first observed as the key factors for PAG adsorption to achieve high adaptability.CONCLUSION: Generally, considering the comprehensive performances, PAG would have higher adaptability in the efficient purification of different concentrations and different temperatures of Cu(II)-containing wastewater. It would thus have better application in different water environments and be regarded as a better adsorbent alternative.
