“…To increase the efficiency of separation, it is desirable to develop effective separation resins for Pu(IV), as well as other resins for metal ions. [8][9][10][11][12] Microbial metabolite desferrioxamine B (DFB), a trihydroxamate-based siderophore produced by the actinobacteria Streptomyces pilosus, has a very strong chelating ability for many high-valence ions under certain conditions. [13][14][15] For instance, it has been reported that DFB chelates with Pu(IV), 13,14 Am(III), 16 Cm(III), 17 and U(VI) 15 in aqueous solution.…”

The adsorption properties of Pu(IV), Am(III), Cm(III), and U(VI) on desferrioxamine B-immobilized micropolymeric resin (DMPs) and adsorbed species were elucidated using thermodynamic constants and log β values. This allowed the determination of adsorption characteristics (91, 95, 88, and 97% for Pu(IV), Am(III), Cm(III), and U(VI), respectively) and individual pH-independent adsorption properties. Pu(IV) could be separated from Am(III), Cm(III), and U(VI) at pH 2. The separation of Pu(IV) from Am(III), Cm(III), and U(VI) was achieved by controlling the pH of the solution using a single resin.

Microfluidic paper-based analytical devices (μ-PADs) fabricated in Japan were employed for the determination of total chromium (Cr) in water, soil, and lettuce irrigated with wastewater in Ethiopia. The μ-PADs, which were printed by wax printing in Japan, were transported to Ethiopia followed by preparation for the determination of total Cr by adding appropriate reagents to the pretreatment and detection zones. Soil and lettuce samples were determined by the μ-PADs and a UV-Vis spectrophotometer in Ethiopia. The paired t-test showed that the mean total Cr concentrations determined in the soil and lettuce samples were not significantly different between μ-PADs and UV-Vis spectrophotometric analysis at the 5% level of significance. This implies that the μ-PADs has good accuracy and reliability and could be employed to monitor Cr in environmental samples. We found that the total Cr concentrations in all soil and lettuce samples were above the permissible limit. Moreover, the evaluation of Cr contamination level using the geo-accumulation index indicated that the soils are contaminated with Cr moderately to heavily. Thus, the present work successfully demonstrated the potential remote investigation of pollution in a less-equipped laboratory by transporting the μ-PADs fabricated in another laboratory.
