TL;DR: Fe3O4@SiO2-NH2 magnetic particles with core-shell structure were attached on carboxylated biochar derived from phoenix tree leaves to synthesize a novel magnetic biochar for removing Cr(VI) ions from acidic solutions as discussed by the authors.

TL;DR: In this paper, a one-part geopolymer was synthesized from alkali-thermal activated Bayer red mud (RM) with addition of silica to optimize its composition, but the longterm strength of the binder with only RM was poor because of the unstable polymerization due to the low SiO 2 /Al 2 O 3 molar ratio.

TL;DR: A two-step mechanism of Fenton oxidation and Fe(III) coagulation was proposed in sewage sludge conditioning, indicating that the coagulations by Fe(3+) species in Fenton reaction could play an important role, compared to traditional Fenton oxidisation effect on sludge Conditioning.

TL;DR: In this article, a review of recent studies on the recycling of spent lead paste and describes novel technologies is presented, including paste-to-paste recycling and hydrogen-lead oxide fuel cell method.

TL;DR: The economic assessment for a wastewater treatment plant of 370,000 equivalent inhabitants confirms that using red mud conditioning, combined with Fenton's reagent, leads to a saving of approximately 411,000 USD/y or 50.8 USD/t DS comparing with using lime and ordinary Portland cement combined with the traditional treatment.
