This standard specifies methods for the determination of arsenic in zinc concentrates, including hydride generation - Atomic fluorescence spectrometry, AFS and potassium bromate Titrimetric method. Method 1 is suitable for the determination of arsenic content in the range of 0.0050% to 0.80%. Arsenic is reduced by hydride generator and its Fluorescence intensity is measured by Atomic Fluorescence Spectrometer (AFS). Method 2 is suitable for the determination of arsenic content in the range of 0.10% to 2.00%. The potassium bromate Titrimetric method is used for analysis. The standard ensures the accurate determination of arsenic content and is suitable for the analysis of zinc concentrate samples.
