Arsenic and antimony in water and wastewater: Overview
15.03.2015· 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. In general, organic arsenic compounds are significantly less toxic than inorganic forms. The toxicity of arsenic
Arsenic and antimony determination by on-line flow
15.01.2001· Hollow cathode (HC) and conventional flat cathode (FC) glow discharge (GD) optical emission spectrometry (OES) were used as detectors for the determination of arsenic and antimony by on-line hydride generation (HG) in a flow system. Both radiofrequency (rf) and direct current (dc) sources were investigated to produce the discharge. The design of the HC and FC and also the parameters
Arsenic/Antimony Removal Clean TeQ Water
Arsenic (As) and antimony (Sb) both appear in group 15 of the periodic table, with antimony appearing directly under antimony. They have complex chemical behaviours, and both are used as alloying agents. The most common emission of antimony into the human environment is a result of coal burning or antimony smelting, with typically low concentrations in water except for areas affected by acid mine drainage
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.
