AI Technical Summary
Existing technologies are difficult to efficiently utilize antimony flue dust to directly prepare high-quality antimony pentoxide precursors for sodium pyroantimonate, and also suffer from high energy consumption and high cost.
Antimony ash is oxidized with hydrogen peroxide in dilute nitric acid solution, combined with ultrasonic-assisted treatment, followed by the addition of concentrated sulfuric acid to remove lead, and then arsenic pentoxide is prepared by spray pyrolysis, thus achieving efficient conversion of antimony and effective removal of impurities.
The preparation of antimony pentoxide precursor with high conversion rate was achieved, which reduced production costs, improved resource utilization, and enabled the recycling of dilute nitric acid solution.
