ActiveDetermination for speciation of 12 elements such as copper, zinc, cadmium, lead and chromium in waste chemicals—Sequential extraction procedure
废弃化学品中铜、锌、镉、铅、铬等12种元素形态分布的测定 连续提取法
Application Summary AI generated
This standard specifies a sequential extraction procedure for determining the chemical speciation (e.g., exchangeable, reducible, oxidizable, residual fractions) of 12 elements, including copper, zinc, cadmium, lead, and chromium, in waste chemicals. It is applied in environmental monitoring and waste management contexts to assess the mobility, bioavailability, and potential ecological risk of heavy metals in industrial solid wastes, sludges, and chemical residues. The method supports regulatory compliance and risk assessment for hazardous waste treatment and disposal.
