Abstrakt:	Iron phosphate@talc (IPT) sorbent was fabricated by precipitation method and utilized for 137Cs, 152+154Eu, and 131Ba sorption from aqueous media. Different analytical apparatuses such as XRD, FT-IR, SEM, and XRF were used to find the structure, morphology, and functional groups of IPT sorbent. Different parameters like shaking time, pH, temperature, and initial metal concentrations were studied. The obtained data reveal that the sorption of 137Cs, 152+154Eu, and 131Ba was pH, time-dependence, and kinetics following pseudo-2nd-order kinetics. The Langmuir and Freundlich equations were used as model isotherms. Thermodynamics parameters were calculated to prove that the sorption reaction was spontaneous and endothermic.
