摘要
摘要本研究研究了二磷酸铁钾纳米颗粒KFeP2O7的合成,将其植入由玉米芯碎片制成的活性炭上。采用x射线衍射(XRD)、扫描电镜(SEM)和透射电镜(TEM)对活性炭/二磷酸铁钾(AC/KFP)复合材料的化学组成和结构进行了分析。进行补充试验以确定表面特性,如表面积和零电荷点(pHpzc)。此外,酸碱滴定法可以确定AC/KFP复合材料的表面位点密度。然后采用间歇法测试了AC/KFP复合材料对U(VI)的吸附性能。Resumen。Este trabajo呈报了síntesis de nanopartículas de difosfato de potasio-hierro, KFeP2O7,植入物sobre carbón activado preparado a partite de restores de olote maíz。La composición química y La structura del compósito de carbono activado/difosfato de potasio-hierro (AC/KFP) se analizó mediante Difracción de Rayos X, Microscopía Electrónica de Barrido y Microscopía Electrónica de Transmisión。这些实现过程是互补的para determinia las características de la surface, como el área de la surface y el punto de carga cero (pHpzc)。Además, la valoración ácido-base permitió确定的la密度和表面的情况compósito AC/KFP。此外,本文还研究了三聚氰胺吸附剂的吸附性能(compósito AC/KFP)和U (VI)氟的吸附性能评价。
Synthesis, Characterization and Adsorptive Properties of Activated Carbon/KFeP2O7 Composite
Abstract. This work deals with the synthesis of nanoparticles of iron-potassium diphosphate, KFeP2O7, implanted on activated carbon produced from corncob debris. The chemical composition and structure of activated carbon/potassium-iron diphosphate (AC/KFP) composite was analyzed by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Complementary tests were conducted to determine surface characteristics such as surface area and point of zero charge (pHpzc). Further, the acid-base titration enabled to determine the surface sites density of AC/KFP composite. Adsorptive properties of AC/KFP composite vis à vis U(VI) was then tested using the batch method.

期刊介绍:
The Journal of the Mexican Chemical Society (J. Mex. Chem. Soc.) is a scientific, blind, peer reviewed, and open access, free of charge publication that covers all areas of chemistry and its sub-disciplines (i.e. medicinal chemistry, natural products, electrochemistry, material science, computational chemistry, organic chemistry, bionirganic chemistry, etc). It is devoted to facilitating the worldwide advancement of our understanding of chemistry. It will primarily publish original contributions of research in all branches of the theory and practice of chemistry in its broadest context as well as critical reviews in active areas of chemical research where the author has published significant contribution. The J. Mex. Chem. Soc. is a quarterly publication which language of submission and publication is English. To be suitable for publication in J. Mex. Chem. Soc., manuscripts must describe novel aspects of chemistry, high quality of results and discussion an excellent bibliographic support, and contribute to the development of the field. Routine or incremental work are not suitable for publication in J. Mex. Chem. Soc. Authors are encouraged to send contributions in electronic form. Our online submission system guides you stepwise through the process of entering your article details and uploading your files.
