Table 1

Kinetic studies of ³²P adsorption onto the GK/M nanocomposite. Showing experimental (EXP), pseudo-first-order kinetic model (KM1), pseudo-second-order kinetic model (KM2) values of the equilibrium uptake capacity 𝑞_𝑒, and model related quantities (Section 2.5). Units: 𝑞_𝑒 (GBq/g), 𝑘₁ (1/min), and 𝑘₂ (g/TBq/min).
