This standard specifies a method for the determination of antimony content in tin concentrates, which is applicable to the determination of antimony content in the range of 0.005% to 0.050%. Specimens were analyzed by sodium peroxide analysis using the malachite green Spectrophotometric method, spec-trophotometry and flame atomic absorption spectroscopy (AAS). Antimony complexes measure Absorbance at a wavelength of 635 nm, and citric acid and ammonia water can be used to mask and separate interfering substances if necessary. The standard provides detailed reagent preparation, experimental procedures and instrumental requirements, providing technical support for the accurate determination of antimony content in tin concentrates.
