This study examined the utilization of spent coffee grounds with different aqueous extraction methods for bioelectricity generation from coastal benthic sediment through a microbial fuel cell (SMFC) system. Different SCGs were evaluated, including rinsing and drying SCG (SMFC-CRD), immersion, (SMFC-CRID), alone (SMFC-CD), untreated (SMFC-C). The caffeine concentration in was significantly reduced using pretreatments, SMFC-CRID achieving lowest 0.021 ± 0.001 mg/g. SMFC-CRD contributed to...
In the present study, we experimentally investigated removal of hydrogen sulfide using steel-making slag (SMS) and clarified mechanism with SMS. The results proved that SMS is able to remove dissolved in water, maximum amount per unit weight for 8 days was estimated be 37.5 mg S/g. processes were not only adsorption onto SMS, but oxidation precipitation as sulfur. chemical forms adsorbed sulfur manganese ratio 81% 19%, respectively. It demonstrated here a promising material remediate...
The species Niphon spinosus (Cuvier, 1829) is the only representative of family Niphonidae and genus Niphon, its taxonomic history complicated; it still unclear in a phylogenetic sense. In this study, we report complete mitochondrial genome N. (OP391482), which was determined to be 16,503 bp long with biased A + T contents (53.8%) using next-generation technology. typical set 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA one control region (D-loop) are included genome. H-strand...
Approximately 300,000 tons of waste oyster shells (OS) are generated annually in the Republic Korea. Comprehensive research is required on effects OS coastal environments for direct application OS. This study aimed to investigate physicochemical property changes sediments caused by calcined were pyrolyzed at 300 °C, 600 and 800 mixed with sediment 10% (P31, P61, P81), 20% (P32, P62, P82), 30% (P33, P63, P83). The sediments’ calcium content varied depending calcination temperature mixing...
Permeability is an important aspect of sediment remediation. It well-known that oyster shells can be used for remediation, however the influence pyrolysis temperature on permeability remains unknown. In this study, we examined and remediation using crushed less than 5 mm in size were pyrolyzed at 350 °C (POS350) 600 (POS600) six hours. Based results variable head test, POS600 has greater POS350. addition, POS350 to reduce dissolved inorganic nitrogen (DIN; NH3-N, NO2-N, NO3-N) phosphate...
In Japan, 15 million tons of steelmaking slag is produced annually as a by-product the process. It known that has specific properties to decrease hydrogen sulfide in seawater. To date, however, mechanism still unknown. This first report explains process reducing level.We added artificial seawater containing ion and obtained fine particles. We analyzed reaction products with X-ray absorption structure (XAFS) scanning electron microscopy-energy dispersive detector (SEM-EDX) confirmed...
