摘要: A hydride generation method was developed for the determination of Sb(III), Sb(III)-S and Sb(V) species in natural waters, has been applied to waters interstitial Saanich Inlet. In oxic dissolved antimony exists primarily as (1.2–1.4 nM) with a few percent Sb(III) (.01–.07 nM). production occurs photic zone probably accounts its concentration at levels greater than those predicted from equilibrium considerations. Even low H2S bottom there is no significant reduction Sb(III). However, up 0.15 nM found there. upper 10 cm reducing very large release Sb particulate matter. At least 50% + Sb(III)-S. The remainder most thioantimonate. This diffuses overlying where it rapidly oxidized Sb(V). deeper portions sediment, resedimented perhaps sulfide or associated iron precipitation.
