Iron oxide (Fe 2 O 3 ) nanoparticles are synthesized by novel, swift, extremely simple, requiring enormously less preparation time, and a financially savvy process called an ASH Supported method and utilized for expelling arsenic from water. A simulated sample of arsenic(III) of known concentration is prepared in the laboratory. This simulated sample of arsenic is treated with two different concentrations and phases of iron oxide nanoparticles for two different reaction times (1 and 24 h). Fe 2 O 3 nanoparticles are observed in two phases, namely mixed and pure phase, in nanosized range confirmed by angle dispersive X‐ray diffraction (ADXRD). These nanoparticles are found to have 99% sorption efficiency and the highest adsorption capacity of 964 mg g −1 for arsenic(III) than reported earlier in any literature. The results show that 0.1 mg of Fe 2 O 3 nanoparticles effectively remove arsenic(III) from the simulated water sample for 1 h reaction time. The maximum adsorption is obtained at a 7.0 pH value for minimal ionic strength. This article also renders that the arsenic removal is phase induced rather than size induced. Arsenic(III) removal by iron oxide nanoparticles synthesized by the above‐mentioned method is reported for the first time and this is the main attraction of the present work.
