- •
As(V) and Se(VI) in high-salinity flowback water was effectively removed by ZVI.
- •
As(V) removal was less susceptible to ionic strength variations than Se(V).
- •
Competing anions in groundwater and stormwater caused insignificant desorption.
- •
As(V) and Se(VI) competition depended on their molar ratio and ZVI surface sites.
- •
Surface characteristics of ZVI were unaffected by molar ratio and dissolved oxygen.
