antimon – Lex
Antimon er et grundstof med atomnummer 51 i gruppe 15 i det periodiske system med atomtegn Sb af latin stibium t er et sølvhvidt, sprødt metal med lavt smeltepunkt, og det anvendes blandt andet til at give legeringer øget hårdhed. Der findes dog ikke-metalliske allotrope former, som er ustabile. Såvel grundstoffet som dets forbindelser er giftige.

Role of trivalent antimony in the removal of As, Sb, and Bi …
The role of trivalent antimony was investigated in removing As, Sb, and Bi impurities from a copper electrolyte. Purification experiments were carried out by adding a various concentrations of Sb(III) ions in a synthetic electrolyte containing 185 g/L sulfuric acid, 45 g/L Cu2+, 10 g/L As, and 0.5 g/L Bi under stirring at 65°C for 2 h. The electrolyte was filtered, and …

Exploring the role of extracellular polymeric substances in the ...
Abstract The concentration of Sb bearing tailings in water located in abandoned antimony mines was found to be a big problem, as they contaminate other water resources and entire food chain. Microorganisms were found to be key in tailing leaching and reaction speeding in the presence of extracellular polymeric substances (EPS) produced by bacteria. Herein, we …
