 The researchers found that the amber-light XAD-7 resin impregnated with cyan-X272 had high affinity for cerium and lanthanum ions, allowing them to be removed efficiently from aqueous solutions. This resin showed good stability over multiple absorption-disoption cycles and could be easily regenerated. Additionally, the researchers found that the resin had a high capacity for cerium and lanthanum ions, making it ideal for industrial applications.
