Sorption of fission products onto polycondensed aluminosilicates (PC-AS_(s)) is a relatively recent and gets out the mechanisms by which the formers are trapped. Here, PC feldspar (PC-FD), perlite (PC-PR) and their blend (PC-FDPR) were synthesized by the alkaline activation using Na-/K-silicates at Si-modulus of 1.35. XRD patterns revealed the semi-crystalline natures of sorbents. Na- and K-feldspars were detected in PC-FD while Na-based carbonate crystals were detected in others. Components of the poly(sialate-disiloxo) structure were detected in FT-IR spectra. Thermographs were deconvoulted and the amounts of the sticking and zeolitic water were estimated. Kinetic batches for sorption of ¹³⁴Cs and ^152+154Eu onto the elaborated yields were constructed. Ranking of sorbed amounts (q_e) was varied from ¹³⁴Cs (PC-FDPR>PC-FD>PC-PR) to ^152+154Eu (PC-PR>PC-FD>PC-FDPR). Maximum q_e was recorded at elevated temperature (323K) to be 4.28 and 1.45 mg/g for ¹³⁴Cs/PC-FDPR and ^152+154Eu/PC-PR, respectively. Along all batches, chemi-sorption mechanism is common denominator. The effective diffusion coefficients (D_i) were in the order of 10^-14 m²/s. Both PC-FD and PC-FDPR recorded greater D_i values of ¹³⁴Cs than ^152+154Eu. The low values of E_a (kJ/mol) reflected the weak adsorbats-adsorbents interactions. While, the high negative values of ∆S^‡ suggested that the studied radionuclides were sorbed in associative reaction mechanism

裂变产物在聚缩铝硅酸盐（PC-AS _（s））上的吸附是一个相对较新的技术，它摆脱了前者被困的机制。在此，使用Na- / K-硅酸盐以1.35的Si模量进行碱活化，合成了PC长石（PC-FD），珍珠岩（PC-PRPR）及其混合物（PC-FDPR）。XRD图谱显示了吸附剂的半结晶性质。在PC-FD中检测到Na-和K-长石，而在另一些中检测到Na-基碳酸盐晶体。在FT-IR光谱中检测到聚（唾液酸-二硅氧烷）结构的组分。将热像仪去卷积，并估计粘着和沸石水的量。动力学批次吸附¹³⁴ Cs和构建了^{152 + 154} Eu的精细产量。吸附量（q _e）的等级从¹³⁴ Cs（PC-FDPR> PC-FD> PC-PR）变为^{152 + 154} Eu（PC-PR> PC-FD> PC-FDPR）。¹³⁴ Cs / PC-FDPR和^{152 + 154} Eu / PC-PR在高温（323K）下记录的最大q _e分别为4.28和1.45 mg / g 。在所有批次中，化学吸附机制都是共同点。有效扩散系数（D _i）为10 ^-14 m ² / s。PC-FD和PC-FDPR都记录了更大的D _i值¹³⁴Cs大于^{152 + 154} Eu。E _a的低值（kJ / mol）反映了弱的吸附物-吸附剂相互作用。而∆ S ^‡的高负值表明所研究的放射性核素被吸附在缔合反应机理中
