Arsenic (As) contamination in the groundwater of Bangladesh is one of the major public health concerns. It has become a challenge to remove As from groundwater and a great deal of efforts employed in this regards with limited success. Cerium oxide is one of the important medias of arsenic removal techniques. Nine units of cerium-based arsenic technology were tested with seven different well wat...

In this study, a Fe-based amorphous metallic coating (AMC) was sealed with three sealants, i.e., stearic acid, aluminum phosphate and cerium salt, respectively. Two types of electrochemical tests, namely the ex situ impedance spectroscopy test in potentiostatic polarization test, were conducted to evaluate erosion–corrosion resistance as-sprayed as-sealed AMCs. The results show that phosphate–s...

We demonstrate the in vivo formation of nano-particulate Ce-containing structures in lungs instilled with 5 mg/kg CeCl3 using high resolution electron microscopy (HRTEM), energy loss spectroscopy (EELS), and elemental mapping (EDS). The observed high lung retention of Ce after instillation of CeCl3 (75-92% retained at 28 days) is unexpected since metal ions are usually readily transported acros...

Reconstructing redox conditions in the paleo-ocean is essential to understand Earth’s biogeochemical evolution. Cerium (Ce) anomaly marine sediments has been used distinguish oxic versus anoxic depositional environments Paleo-ocean. Previous studies suggested that dissolved oxygen indispensable cerium oxidation. Therefore, this reaction can be thermodynamically modeled quantify contents ocean. ...

A simple, sensitive, and selective online pre-column derivatization high-performance liquid chromatographic method was developed and validated for the first time to determine trace levels of folic acid (FA). An oxidant cerium (IV) trihydroxyhydroperoxide packed reactor was used for pre-column oxidation and was combined by column switching with a C18 analytical column for sample enrichment and s...
