1. Introduction. Lead anode slime (LAS) is a hazardous waste that is typically generated during the electrolytic process of crude lead (Gao et al., 2023).LAS was classified as a hazardous waste under the number HW48 due to its high content of heavy metal elements and arsenic (F. Wang et al., 2021).In China, the production of metallic …
