Removal of inorganic arsenic species from wastewater by rapid adsorption technology is extremely desirable in the fields of sewerage treatment because of its high efficiency.Herein,FeMn composite oxides with varied Fe/Mn molar ratios as adsorbents were prepared via thermal decomposition of their oxalates precursors.The FeMn composite oxalate was used as the precursor to obtain the composite oxide with uniform distribution of iron and manganese elements through thermal decomposi-tion,and the iron manganese composite oxide was used as the adsorbent to adsorb inorganic arsenic in wastewater.With the aid of ultrasound,the removal effect of iron manganese composite oxide on inorganic arsenic in wastewater was remarkable.The experimental results showed that the FeMn composite adsorbent with n（Fe）:n（Mn）=6:4 exhibited above 95% of arsenite removal efficiency under ultrasonic wave within 1 min owing to its high specific surface area（396.6 m2/g） and unique morphology.The study of adsorption kinetics showed that the adsorption process conformed to the quasi second-order kinetic model,and the adsorption rate constant was 1.11 g/（mg·s）.The regeneration experiment of adsorbent showed that the adsorbent adsorbed arsenic was eluted with NaHCO3 solution and reused in the adsorption experiment.The adsorption rate of arsenic could still reach 83.6% after the adsorbent was reused for 3 times.
