Arsenic trioxide is also proven to be useful in criminal homicides due to its characteristic, which is tasteless, colorless, highly toxic, and soluble in water [2, 4]. The high usage of arsenic trioxide in suicide cases had made it to be often referred as the “inheritance powder” in the 18th century .

Arsenic trioxide was recovered from the alkaline leachate by acid precipitation, at an optimal H 2 SO 4 /arsenic ratio of 1.9 mol/mol; after washing with diluted acid, the purity of arsenic trioxide reached 93.4 % and the total recovery ratio of arsenic was 79 %. This relatively simple process was found to be an effective method for arsenic ...

The removal of Sb(III) from waste water is achieved in batch system by using grey and red Erzurum (Oltu) clay which are cheap and natural adsorbents. Adsorption experiments were studied. For this purpose, various important parameters such as contact time, pH, and temperature were examined on the adsorption of Sb(III) ions onto grey and red Erzurum (Oltu) clay. Decreasing amount of Sb(III) ions ...

For the recovery of alkali and arsenic, Jin et al. (1999) proposed that a process of arsenic removal with CaO, arsenic leaching with H 2 SO 4, reduction and cooling crystallization was used to dispose arsenic-alkali solution, which can obtain the products of arsenic trioxide and sodium hydroxide. However, the calcium arsenate residue obtained ...

2019-12-12 · Anode slime is an important material of recycling precious metals. Up to now, treating the arsenic- and antimony-rich anode slime by conventional processes has the following problems: its economic and environmental effect is less than satisfactory, and the removal effect of arsenic and antimony from anode slime in present processes is not all that could be desired. Therefore, vacuum …
