AB  - This work investigates the adsorption mechanism of alachlor and pentachlorobenzene on chars (hydrochars and biochars) originated from Miscanthus giganteus and sugar beet shreds. Two different processes were used: hydrothermal conversion at three temperatures (180, 200, and 220 degrees C) and slow pyrolysis at 400 degrees C. Specific surface area (SSA) for all investigated chars ranged 3.87-260 m(2)/g, whereby biochars had a higher SSA. For hydrochars from sugar beet shreds, both the SSA (3.87-5.53 m(2)/g) and pore volume (0.023-0.0277 cm(3)/g) increased with increasing temperature, while the opposite trend was observed for hydrochars from miscanthus. The opposite trend could be a consequence of the different chemical composition of the used feedstock such as hemicelluloses and cellulose which can produce volatile organic products at higher temperatures and may cause the reduction of SSA. All adsorption isotherms were well described by the Freundlich model. The nonlinearity of the isotherms ranged from 0.450 to 0.986. K-d values for both investigated compounds followed the order: hydrochars from sugar beet shred  LT  hydrochars from miscanthus  LT  biochars, implying that the SSA of the chars affects the adsorption mechanism. In general, all the investigated adsorbents demonstrated higher adsorption affinity for pentachlorobenzene in comparison with alachlor, implying that hydrophobic interactions enhanced the adsorption of the more hydrophobic organic compound. In addition, for all hydrochars, adsorption affinities for the smaller pentachlorobenzene are significantly greater than for the larger alachlor, probably due to its ability to better penetrate into the pores of the adsorbents. This type of research is necessary to obtain safe adsorbents for water remediation.

AB  - This work investigates the transport behaviour of selected organophosphorus pesticides, OPPs (chlorpyrifos, CP; chlorpyrifos-methyl, CPM; chlorfenvinphos, CF) through Danube alluvial sediment in the presence of hydrochars and biochars. The investigated hydrochar, obtained at three different temperatures (180 degrees C, 200 degrees Cand 220 degrees C), originated from sugar beet shreds (SBS) and Miscanthusxgiganteus (MIS). Results are described by conventional advective-dispersive equation (ADE). Retardation coefficients (R d ) for all OPPs were in the range 6.2-16. Biodegradation was 4.15 and 1.80 for CPM and CP, respectively, while for CF biodegradation did not occur. The addition of carbon rich materials increases retardation of all OPPs in the range from 4 to 18 times depending on the material. Column experiment results indicated that biodegradation of OPPs occurred (up to lambda = 13). In order to confirm that biodegradation occurred in the column experiments, we isolated OPPs degrading microorganisms for the first time from the alluvial sediment. A strain capable of degrading CP and CPM was isolated and identified as Bacillus megaterium BD5 based on biochemical properties, MALDI TOF and 16S rRNA analysis (99.54% identity). The results demonstrate that hydmchars, biochars and isolated degrading bacteria may be effective agents for reducing the mobility of or removing OPPs in contaminated soils or sediments.
