Abstract Humic acid (HA) was used to represent natural organic matter, and the effects of Iron ions (Fe(II)/Fe(III)) on the complexation of HA with arsenic (As(V)/As(III)) of different molecular weights were investigated by equilibrium dialysis and ultrafiltration, and the complexation characteristics were characterized by infrared spectroscopy (FT-IR). Both Fe(II) and Fe(III) enhanced the As complexation ability of HA, and the enhancement effect on As(V) complexation ability was greater than that of As(III); pH significantly affected the As complexation ability of HA; the percentage of As complexation increased with the increase of dissolved organic carbon (DOC) concentration of HA from 50 to 200mg/L, and the percentage of HA-Fe(III) complexation was the maximum at 24.55%. Increasing the initial As concentration from 10μg/L to 1000μg/L, the percentage of As complexation decreased, with the minimum As(III) complexation percentage by HA-Fe(III) at 3.11%. Under the same environmental conditions, the percentage of As complexed with molecular weight more than 100kDa was the highest, and the percentage of As(III) complexed at HA-Fe(II) was 26.43%; The percentage of As complexed at HA with molecular weight less than 10kDa was significantly higher than that at other molecular weights. The enhancement of Fe was mainly due to the formation of a bridge between Fe and carboxyl groups of HA and then complexation with As to form a ternary complex.
