Differences between reductive defluorination of perfluorooctanoic acid by chlorination, bromination, and iodization in the vacuum-ultraviolet/sulfite process.

Exploring the role of Fe species from biochar-iron composites in the removal and long-term immobilization of SeO against competing oxyanions.

Carbothermal reduction is a convenient and cost-effective method to produce biochar (BC) supported iron-based nano-particles (INP) for oxyanion contaminants removal.
