SUMMARY

• The generation of composite materials by combining natural clinoptilolite and BaSO4 to remove 137Cs and 90Sr simultaneously.
• Improvement solid/liquid separation degree with the help of fast sedimentation of composite coagulants for waste volume reduction, which facilitates waste encapsulation for safe long-term waste management.
• The process intensification of the proposed method by using an agitated tubular reactor for enhanced ion removal while reducing plant footprint, cost and waste generation.
