TL;DR: This work identifies a complex, nutrient-rich organic coating on co-composted biochar that covers the outer and inner (pore) surfaces of biochar particles using high-resolution spectro(micro)scopy and mass spectrometry, which strengthens biochar-water interactions and thus enhances nutrient retention.
Journal ArticleDOI
Water extractable organic carbon in untreated and chemical treated biochars.
TL;DR: Water extracts obtained from twelve non-herbaceous biochars were tested by Liquid Chromatography - Organic Carbon Detection (LC-OCD) to identify the effects of both pyrolysis conditions and chemical treatments on WEOC content, and the utility of LC- OCD is demonstrated in providing an understanding of how biochar additions to soil can alter DOC.

Direct comparison of ozonation and adsorption onto powdered activated carbon for micropollutant removal in advanced wastewater treatment
TL;DR: Comparing typical doses for practical applications ozonation proved to be more efficient for abatement of sulfamethoxazole, while removal of benzotriazole and iomeprol was comparatively more efficient with activated carbon and DOC-normalized doses were also applied to PAC and correlated better to relative OMP removal than volume proportional PAC addition.

Molecular weight, polydispersity, and spectroscopic properties of aquatic humic substances.
TL;DR: Data indicate that aquatic fulvic acids, a commercial humic acid, and unfractionated organic matter from four natural water samples are smaller and less polydisperse than previously believed.

Removal of bulk dissolved organic carbon (DOC) and trace organic compounds by bank filtration and artificial recharge.
TL;DR: It was found that redox conditions and travel time significantly influence the DOC degradation kinetics and the efficiency of AOX and trace compound removal.
