A method for solidifying spent tributyl phosphate and kerosene (TBP/OK) organic liquids in a phosphate acid-based geopolymer (PAG) was investigated. The TBP/OK emulsion containing tween 80 (T80), TBP/OK organic liquids, and H₃PO₄ was prepared. The TBP/OK emulsion was mixed with metakaolin to obtain solidified TBP/OK forms (SPT). The compressive strength of the SPT was up to 59.19 MPa when the content of TBP/OK was 18%. The loss of compressive strength of SPT was less than 10% after immersion and less than 25% after freeze-thaw treatment. The final setting time was 40.0 h, and the shrinkage of SPT was nearly 3%. The leaching test indicated that the release of TBP/OK from hardened SPT was limited. Characterization of SPT suggested that solidification of TBP/OK using PAG occurred by physical encapsulation.

废酸式TBP / OK有机液体在磷酸基地质聚合物中的固化和稳定化

研究了一种在磷酸基地质聚合物（PAG）中固化废磷酸三丁酯和煤油（TBP / OK）有机液体的方法。TBP / OK乳液，包含吐温80（T80），TBP / OK有机液体和H ₃ PO ₄准备好了。将TBP / OK乳液与偏高岭土混合以获得固化的TBP / OK形式（SPT）。当TBP / OK含量为18％时，SPT的抗压强度可达59.19 MPa。浸泡后，SPT的抗压强度损失小于10％，冻融处理后小于25％。最终凝固时间为40.0 h，SPT的收缩率接近3％。浸出试验表明，TBP / OK从硬化的SPT中的释放受到限制。SPT的表征表明，使用PAG固化TBP / OK是通过物理封装实现的。
