Research progress of antimony

In the present study the removal of common antimony species in water, namely, Sb(III) and Sb(V), was investigated by the addition of iron-based coagulants.

The new tool developed in this study for the removal of Sb has a huge potential to treat Sb in agricultural lands. For instance, salicylic acid which plays a critical role in plant defenses is reported to reduce in the presence of Sb (Zhu et al., 2022) and this problem is common for rice farmers who produce rice in wetlands/waterlogged conditions.

However, antimony has high cumulative toxicity and carcinogenicity in humans [3,4]. Therefore, to protect human health, many countries and organizations have listed antimony as a priority pollutant [5]. The United States requires that the antimony content in drinking water must be <6 μg/L, and the European Union stipulates that it is 5 …

Though there has been a dramatic increase of studies on antimony removal, few studies evaluated the feasibility of treating actual wastewater under the influence of multiple co-existing ions (Yang et al. 2019). Cost efficiency of different types of adsorbents was rarely mentioned (Ungureanu et al. 2015).
