Arsenic trioxide is indicated in combination with tretinoin for treatment of adults with newly-diagnosed low-risk acute promyelocytic leukemia whose acute promyelocytic leukemia is characterized by the presence of the t(15;17) translocation or PML/RAR-alpha gene expression; and for induction of remission and consolidation in patients with acute promyelocytic leukemia who are refractory to, or ...
Arsenic trioxide powder.. Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table.The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds.
In the 1860s, an arsenic byproduct of dye production, London Purple, was widely used. This was a solid mixture of arsenic trioxide, aniline, lime, and ferrous oxide, insoluble in water and very toxic by inhalation or ingestion [75] But it was later replaced with Paris Green, another arsenic-based dye. [76]
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
The Marsh test treats the sample with sulfuric acid and arsenic-free zinc. Even if there are minute amounts of arsenic present, the zinc reduces the trivalent arsenic (As 3+). Here are the two half-reactions: Oxidation: Zn → Zn 2+ + 2 e − Reduction: As 2 O 3 + 12 e − + 6 H + → 2 As 3− + 3 H 2 O. Overall, we have this reaction:
Arsenic oxide may refer to any of the following: Arsenic dioxide, As 2 O 4; Arsenic trioxide, As 2 O 3; Arsenic pentoxide, As 2 O 5
The bulk of the plantings should however be native plants. Native plants have a job to do, non-natives not so much. More: Ask the Master Gardener: Want to garden while living in an apartment? Here ...
Medical use of arsenic trioxide refers to the use of arsenic trioxide (Latin: Arsenum trioxydatum, [1] also known as "arsenic") as an chemotherapeutic agent in the treatment of acute promyelocytic leukemia. Arsenic trioxide has orphan drug status [2] and is available as the pharmaceutical preparation Trisenox.
