Exploring the interference mechanisms of surface and aqueous complexes with groundwater arsenate and arsenite adsorption
Ca 2+ , Mg 2+ , and HCO 3 − are extremely common coexisting ions with arsenic (As) in geogenic As-polluted groundwaters. Although extensive research has improved our knowledge of groundwater As removal techniques and mechanisms, there is still a lack of a definite explanation of the distinct influen...
