Denitrification with As(III) (3.5 mM) adsorbed to activated aluminum. The formation of N2-N (panel A) by NGS. Legend for panel A: full treatment with As(III) and NO3− (▲); endogenous control with only NO3− added (△); and the abiotic control As(III) and NO3− (○); Panel B shows the consumption of NO3− and the temporal accumulation of NO2−. Legend for panel B: NO3− consumption in the full treatment with As(III) and NO3− (▲); NO3− consumption in the endogenous control with only NO3− added (◆); NO3− consumption in the abiotic control with As(III) and NO3− (●); NO2− accumulation in the full treatment with As(III) and NO3− (△); NO2− accumulation in the endogenous control with only NO3− added (◇); NO2− accumulation in the abiotic control (○) with As(III) and NO3−. No N2O was observed in any treatment.
