Abstract BACKGROUND Ambrosia trifida L. (buffalo‐weed) is a ubiquitous invasive plant species in Korea, causing severe allergy problems to humans and reduction crop yields. Converting buffalo‐weed biomass biochar its use as an adsorbent for the depuration of trichloroethylene ( TCE ) contaminated water could help resolve two existing environmental issues simultaneously . RESULTS The was converted at 300 °C BC300 700 BC700 ). pyrolysis temperature strongly influenced properties resulting...
Exchangeable lead (Pb) extracted by ammonium acetate from three independent incubation studies was assessed to understand the influence of feedstock, pyrolysis temperatures, and production conditions on Pb immobilization capacities different biochars. Vegetable waste biochar, pine cone, wood bark, cocopeat, red pepper stalk, palm kernel shell were used as feedstocks (food supply agricultural wastes) produce biochars at 200-650 °C with without N2/CO2. Biochars applied 5 2.5% (w w-1) a...
A pilot-scale treatment study was implemented at a deposition site of chromite ore processing residue (COPR) in New Jersey. Ferrous sulfate heptahydrate (FeSO4·7H2O) employed to reduce hexavalent chromium two dosages with three types soil mixing equipment. XANES analyses treated samples cured for 240 days indicated that all combinations failed meet the Cr(VI) regulatory limit mg/kg. More importantly, discrepancy between and alkaline digestion results renders latter unreliable purposes when...
Biochar has an ability to alter the biological, chemical, and physical properties of soil due its physicochemical such as surface area, porosity, nutrient retention ability, available contents, aromaticity, etc. The present study was designed evaluate impact application rate biochar on hydraulic a sandy loam in short term. produced at 500 °C from dried corn residue (BC500). BC500 incorporated rates 0, 2.5%, 5.0%, 7.5%, 10% (w·w−1) into filled up height 4 cm, cores having 5 cm diameter...
