"The dissolution of calcium arsenates in residues released on the premises of an inactive smelter has caused high levels of arsenic pollution in the adjacent down-gradient 6 km of a perched aquifer, reaching up to 158 mg/L ...
Optimizing the differential pulse anodic stripping voltammetry method with hanging mercury electrode for thallium (I) determination in the presence of lead (II) and copper (II) for application in contaminated soils

Cruz Hernández, Yusniel; Villalobos, Mario; González Chavez, José Luz; Martínez Villegas, Nadia Valentina (Universidad Nacional Autónoma de México, Universidad Autónoma de Tlaxcala, Universidad Veracruzana, Universidad Autónoma de Occidente, Centro de Ciencias de la Atmósfera, 2019)

"The conditions that allow thallium (I) determination in the presence of lead (II) and copper (II) were optimized without prior separation of these cations, using a previously developed differential pulse anodic stripping ...
