2019-8-1 · Antimony removal from Cl − and SO 4 2− media as a function of iron dose at a target pH of 5.0 is shown in Figure 3. As seen previously, Sb(III) is easier to remove than Sb(V) from both chloride and sulfate media. Removal of both Sb(III) and Sb(V) is improved by increasing the ferric chloride dose.

2021-9-15 · Choosing a removal method is inseparable from the complicated chemical property of antimony. There are mainly three valence states of − 3, + 3, and + 5 for antimony, among which the negative trivalent antimony is not stable because it is easy to be oxidized (Li and Fu, 2020).However, the relatively stable trivalent antimony and pentavalent antimony usually exist

2019-2-18 · The presence of antimony(III) in water represents a worldwide concern, mainly due to its high toxicity and carcinogenicity potential. It can be separated from water by the use of sustainable biopolymers such as chitosan or its derivatives. The present study applied chitosan modified with iron(III) beads to Sb(III) removal from aqueous solutions.

2020-11-17 · In this study, diatomite coated with Fe-Mn oxides (DFMO) was synthesized through calcination. The adsorption of antimonate (Sb(V)) by DFMO was studied, and environmental factors affecting the adsorption were investigated. The components of DFMO were identified as γ-Fe2O3, γ-MnO2, and SiO2, in the presence of diatomite covered with nanoscale metal oxides.

2007-5-4 · The removal behavior of antimony from liquid copper by using CuCl-CaO fluxes was observed at 1423 K. It was difficult to remove antimony from liquid copper by using only CuCl flux. However, the addition of CaO to CuCl flux was effective for the removal of antimony. The concentration of antimony decreased with time or with increasing CaO content.

1994-10-28 · If left unchecked, the antimony and bismuth present in the electrolyte will increase to the point where they contaminate the copper cathode. It is therefore necessary, and in fact a general practice in copper electrorefining, to remove antimony and bismuth from the electrolyte. Iron is another metal usually present in copper electrolyte.

2015-2-25 · As shown in Fig. 9a, the core–shell structure was found in NZVI adhering on beta zeolite and EDX results revealed the existence of antimony, so NZVI acted as main active point on NZVI-zeolite and antimony removal mechanism in short term (3 h) was similar with bare NZVI. But, the situation is totally different when reaction was prolonged.
