Antimony contamination, consequences and removal

Jul 30, 2018· Many research articles have paid attention to the effective techniques for Sb removal since the 1970s. Sb is a metalloid, having properties of metal and nonmetal and existing in the environment like arsenic in two oxidation states mainly, i.e., trivalent antimony (Sb(III)) and pentavalent antimony (Sb(V)) ( Shan et al., 2014 ).

A STUDY OF THE ION EXCHANGE REMOVAL OF ANTIMONY(III)

Jul 18, 2013· Several methods have been developed to remove antimony from copper electrolytes. Previous research, however, has focussed almost exclusively on the behaviour of Sb(III), neglecting the fact that Sb(V) is also commonly found in copper electrolytes. In this project, the solubility and the ion exchange behaviour of both Sb(III) and Sb(V) were

An Effective Method to Remove Antimony in Water by Using

The effectiveness of antimony (Sb) removal by using iron-based coagulants was investigated in this study. The effects of pH, coagulant types and dose, equilibrium concentration, co-existing humic acid (HA) and anions, and oxidation process were studied. Effective Sb removal was achieved by using Fe(III)-based coagulants. However, the removal efficiency of Sb by using Fe(II)-based coagulants

Removal of antimony from copper by injection of soda ash

The removal of Sb from molten copper is of importance in the development of processes which can smelt copper concentrates directly into copper in a single furnace. A promising method is injection of oxygen and sodium carbonate in a modified anode furnace. This study encompassed a thermodynamic analysis of the impurity removal reactions and an experimental investigation of antimony removal from

Removal of Antimony(III) from Aqueous Solution by Using

The removal of Sb(III) from waste water is achieved in batch system by using grey and red Erzurum (Oltu) clay which are cheap and natural adsorbents. Adsorption experiments were studied. For this purpose, various important parameters such as contact time, pH, and temperature were examined on the adsorption of Sb(III) ions onto grey and red Erzurum (Oltu) clay.

Based on these, Sb in wastewater could be removed and recovered. The highest removal of Sb (76.1%) was achieved in acidic solution (pH = 4). The formation of stibine was proven to contribute most significantly (66.2%) to the removal of antimony in the solution, while the electro-deposition and adsorption also made a small contribution.
