The adequacy of synthetic Zn–Al-sulphate LDHs to remove arsenic from aqueous systems was tested through sorption experiments, using a series of aqueous solutions with dissolved HAsO 42− together with other anions (Cl − , SO 42− , MoO 42− , HCO 3− , CO 32− ) to assess their competition influence on the As removing process. The...

In such area (about 50km 2 ), previous mining activities caused a serious heavy metal contamination of surface waters, groundwater, soils and biota.
