Antimony (Sb) and arsenic (As) are chemical analogs, but their behaviors in plants are different. To investigate the Sb uptake, translocation and speciation in As-hyperaccumulator P. cretica, a hydroponic experiment was conducted.In this study, P. cretica was exposed to 0.2-strength Hoagland nutrient solution, which contained 0.5 or 5 …
Antimony is a highly toxic pollutant and its removal from water gains increasing attention. To effectively remove both Sb(III) and Sb(V), a novel lanthanum-manganese binary oxide (L 1 M 2 BO) adsorbent was synthesized by a simple oxidation coupled with precipitation method. The as-prepared L 1 M 2 BO was detailedly …

Stibnite, also known as "antimonite," occurs as soft gray color needle-like radiating acicular crystals. Small hydrothermal veins of stibnite are common and big deposits are rare. The mineral is potentially toxic primary sulfide ore of antimony.
Antimonite definition: (mineralogy) A grey mineral, antimony sulfide (Sb 2 S 3 ) that is the main source of antimony ; stibnite. .
This study introduces a series of Fe/Mn-GOCS composites using high-temperature impregnation with graphene oxide and chitosan as substrates, modified by diverse manganese salts, including MnCl2∙4H2O, KMnO4, and MnSO4.

Antimonite (Sb(III)) and antimonate (Sb(V)) are two most frequently detected Sb species in aquatic environment [5] and Sb(V) is 10 times less toxic compared with Sb(III) [6]. The removal of Sb(III) from water is complicated by its weak affinity for coagulants and absorbents resulting from its neutrality over a wide range of pH (2–10.4) [7].
