arsenic antimony discharge

arsenic antimony discharge - noomenadvocatuur.nl

Arsenic and antimony have chemical and toxicological similarities, and pollution from both commonly co-occurs (Fu et al., 2010). The toxicity of arsenic and antimony is dependent on their forms and oxidation states. Arsenic toxicity is directly related to the mobility in water and body fluids of its species.

Arsenic and antimony determination by on-line flow

2001-1-15  Working standard solutions were prepared daily by an appropriate dilution of the respective stock standard solutions of arsenic (III) and antimony (III) of 1000 mg l −1 from Merck (Darmstad, Germany) with 2 M HCl, which was used as the blank. Since the arsenic stock solution used for the experiments was already of As(III), it was not necessary to carry out any analyte pre-reduction step

Mobilisation of Antimony and Arsenic Around

Antimony (Sb) is an element similar to arsenic that forms anions in surface waters, rather than cations like other metals. Little is known about natural mobility of antimony in the environment. However, recent studies have suggested that antimony has similar toxicity to arsenic. Current New Zealand drinking water guideline values are 3 parts per billion...
