Adsorption behavior of the iron impregnated, weakly basic resin D301 (Fe‐D301) for removal of 2‐naphthalenesulfonic acid (2‐NSA) from aqueous solution was studied by using a fixed‐bed column. The effects of process variables such as bed height, flow rate, and coexisting ions were investigated. The results indicated that the breakpoint and exhaustion point increased with increasing bed height and decreased with increasing 2‐NSA flowrate. Experimental data showed a strong fit to the Bed Depth Service Time model. The coexisting ions in the 2‐NSA solution had a clear effect on the breakthrough volume. The high extent of recovery of 2‐NSA with good reproducibility provided an effective method for the separation of 2‐NSA by the adsorbent Fe‐D301.
