Highly efficient Plutonium(IV) uptake from acidic feeds using four extraction chromatography resins containing diglycolamides and ionic liquid

•Four extraction chromatographic resins containing diglycolamide ligands with varying alkyl chain and ionic liquid were prepared.•The XC resins were used for the batch uptake of Pu(IV) with the trend: TPDGA > THDGA > TODGA > TDDGA.•The uptake of Pu(IV) using TPDGA resin was the highest reported with all DGA based resins reported so far.•The reusability studies were encouraging up to five cycles of extraction and stripping.•The Pu(IV) uptake conformed to Langmuir thermodynamic and pseudo-second order kinetic models.•The column studies indicated good breakthrough profiles and sharp elution peaks.
