Article Synopsis
  • The research aims to effectively extract and purify europium (Eu) from nuclear waste using a specially synthesized composite material.
  • Key characterization techniques such as FTIR, TGA, DTA, SEM, and BET were employed, revealing that the optimal Eu removal efficiency of 86.4% occurs at a pH of 4.5 after 180 minutes.
  • The study further indicates that the sorption follows pseudo second-order kinetics and fits the Langmuir isotherm model, demonstrating that this polymer composite is highly effective for recovering radioactive Eu ions from various water sources.

Nano trigonal prismatic BaCoO with hierarchical structure and deficient BaCoO with columnar structure have been prepared at low temperatures (400 [BC4] and 500 [BC5]) °C/3h using green method. X-ray diffraction (XRD) results demonstrate the presence of enriched BaCoO phase at 400 °C and multiphase structures: BaCoO, BaCoO, and CoO with a decrease in the amount of BaCoO at 500 °C. The prepared powders are characterized by a high specific surface area (SSA) values which are reflected to the mode of synthesis that leads to produce materials with massive active sites.

Article Synopsis
  • Copper oxide nanoparticles (CuO NPs), obtained from Aspergillus terreus filtrate, show promise for use in the biomedical field.
  • Characterization techniques like UV-Vis spectrophotometry, FT-IR, XRD, SEM, and TEM confirmed the structure, purity, and shape of the nanoparticles, with an average size of about 15.75 nm.
  • A new composite material was synthesized for the radiochemical separation of Sc(III) ions, achieving a recovery yield of 78% and meeting quality standards for nuclear medicine applications.
