GB/T 38233-2019 "Determination of iron-containing dust, lead and zinc content Inductance-coupled plasma atomic emission spectroscopy (AES) method" standard specifies the use of Inductance-coupled plasma atomic emission spectroscopy (AES) method for the determination of lead and zinc content in iron-containing dust and dust. It is suitable for the determination of lead content in the range of 0.04% to 10% and zinc content in the range of 0.004% to 15%. The standard details the steps of sample analysis, elemental Light spectrum determination and result calculation, providing a scientific basis for the analysis of heavy metals content in iron-containing dust and dust.
