New two-step extraction method in antimony speciation ...

2019-5-1  This is obviously due to the reduction of Sb(V) to Sb(III). After sonication for 30 min in above co-extractant, the recoveries of Sb(III) and Sb(V) in the simulated fiber filter were near 100%. As a result, 30-minute extraction time was the longest extraction time without changing the original form of antimony under the reducing extraction system.
