Removal and recovery of nickel ion in sodium citrate solution with the macroreticular chelating resin containing triethylenetetramine side chain was investigated. The resin (RMT) exhibited high affinity for nickel ion in a solution containing 100 mmol/dm 3 of sodium citrate over the pH range of 7.4–11.5. The adsorption of nickel ion was above 98%. In the column method, the breakthrough capacity of the RMT for nickel ion was 3.0 g/dm 3 ‐resin, when the solution containing 0.5 mmol/dm 3 of nickel (II) nitrate and 100 mmol/dm 3 of sodium citrate was passed through the RMT column at a space velocity of 7.5 h −1 . The nickel ion adsorbed was eluted by allowing 1 mol/dm 3 hydrochloric acid to pass through the column. The recycle of adsorption and elution was found to be satisfactory.
