Biochar and ferromagnetic biochar obtained from the pyrolysis of dried mango seeds modified using a hydrothermal method were used as catalyst for heterogeneous degradation indigo carmine in an aqueous medium. These prepared biochars characterized different techniques: Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) energy dispersive (E...

We come to the recovery concept from 2 different directions. F.F. is a consumer professional who has both a scientific appreciation for schizophrenia as an illness and personal experience of battling both the illness and stigma from mental health professionals and the community. He came to the recovery concept as a function of his personal struggles and growth. A.S.B. is a behavior therapist wh...

The necessity and challenges associated with the new-type photocatalytic Fenton-like system was introduced, followed by discussion of innovation breakthrough self-cyclable photo-Fenton in this highlights. An inspiration towards new-generation decentralized sustainable environment treatment device is expected.

Background: Mature landfill leachate is a complicated mixture which is resistant to biological treatment processes. The treatment of mature landfill leachate by struvite precipitation and Fenton oxidation was the main objective of the current research. Methods: Struvite with the phosphate/ammonia/magnesium molar ratio of 1/1/1.05 was considered during all experiments. Five initial pHs of 3, 4,...

Degradation of polyvinyl alcohol was studied a combination of chemical treatment with Fenton process and biological degradation in anaerobic environment. The experiment was based on different amounts of hydrogen peroxide and of Fe(II) added to water solution of PVA of concentration 200-500 mg.L. Fenton process was monitored by analyzing the total organic carbon (TOC) in the solution. Depending ...

A recently developed Pd-based electro-Fenton (E-Fenton) process enables efficient in situ remediation of organic contaminants in groundwater. In the process, H₂O₂, Fe(II), and acidic conditions (~pH 3) are produced in situ to facilitate the decontamination, but the role of ubiquitous natural organic matters (NOM) remain unclear. This study investigated the effect of Aldrich humic acid (HA) on t...
