Geographic distribution of heavy metals and identification of their sources in soils near large, open-pit coal mines using positive matrix factorization
Journal of Hazardous MaterialsWei Cheng, et. al
2020-04-05
Mining activities are considered the most important factor causing heavy metal accumulation in surface soil and it is important to understand the spatial distribution and source of heavy metals in typical steppes. In this study, the contents, spatial distribution, and sources of heavy metals were determined using geostatistical analyses, multivariate statistical analyses, and a positive matrix factorization (PMF) model using 152 soil samples collected from a grassland near the Sheng-Li coal base.
Biochar-supported nZVI (nZVI/BC) for contaminant removal from soil and water: A critical review
Journal of Hazardous MaterialsShengsen Wang, et. al
2019-07-05
The promising characteristics of nanoscale zero-valent iron (nZVI) have not been fully exploited owing to intrinsic limitations. Carbon-enriched biochar (BC) has been widely used to overcome the limitations of nZVI and improve its reaction with environmental pollutants.
Chemically activated hydrochar as an effective adsorbent for volatile organic compounds (VOCs)
ChemosphereXueyang Zhang, et. al
2019-03-01
Hydrochars derived from hickory wood and peanut hull through hydrothermal carbonization were activated with H3PO4 and KOH to improve their performance as a volatile organic compound (VOC) adsorbent. Polar acetone and nonpolar cyclohexane were used as representative VOCs. The VOC adsorptive capacities of the activated hydrochars (50.57–159.66 mg⋅g−1) were greater than that of the nonactivated hydrochars (15.98–25.36 mg⋅g−1), which was mainly caused by the enlargement of surface area.
