TL;DR: In this article, a nanoscale zero-valent iron (nZVI) supported on biochar (BC) nanocomposite was synthesized using low-cost rice husk through reduction of ferrous iron with sodium borohydride as a reductant under nitrogen atmosphere.

TL;DR: In this article, the authors focused mainly on determining the proportions of heterogeneous catalysis in the copper oxidate/persulfate combined system, and the effects of copper oxidates dosage, persulfate concentration, and initial solution pH on the oxidation of p-chloroaniline (PCA) were evaluated.

TL;DR: The degradation of p -chloroaniline (PCA) by persulfate (S 2 O 8 2 - ) activated with zero-valent iron (ZVI) was investigated through batch experiments as discussed by the authors.

TL;DR: In this paper, it was shown that activated persulfate was main reactive oxygen species generated on copper oxide surface, along with minor sulfate and hydroxyl radicals produced, which indicated the potential applicability of copper oxide for in situ chemical oxidation for two reasons: (1) ubiquitous chloride and bicarbonate ions showed no negative effect and (2) the slight radical generation avoid the persulfates consumption by non-pollutant reductive materials.

TL;DR: In this paper, the effects of different parameters such as pH, ZVI concentration, aniline concentration, persulfate concentration, and reaction temperature on anilines degradation were investigated under laboratory conditions.
