Soil microorganisms play important roles in the dynamic regulation of organic matter in the forest ecosystem and are affected by different revegetation types. To reveal the influence of different revegetation types on soil microorganisms, we examined soil properties, soil microbial activity and diversity in Baishilazi Nature Reserve, including two planted coniferous forests (LG: Larix gmelinii, PK:...
In this work, porous HAP nanofibers assembled from nanorods were developed as potential devices for the treatment of Cu(II), Cd(II), and Pb(II) contamination of consumable waters. Two steps were employed in the HAP nanofibers fabrication. First, rod-like HAP nanoparticles were synthesized through a chemical pathway from Ca(NO₃)₂ ·4H₂O, (NH₄)₂ HPO₄, and polyvinylpyrrolidone (PVP) as a capping agent...
Antimony ore tailings slag was used analyze heavy metals, chemical speciation, and leaching characteristics. The results show that the residual silicate phases account for 65.44% of Sb, 77.22% of As, 87.94% of Hg, 58.53% of Pb, 71.27% of Cd, and 96.34% of Zn. Although the exchangeable and carbonate phases account for 7.71% of Sb, 0.71% of As, 3.77% of Hg, 4.82% of Pb, 1.83% of Cd, and 1.73% of Zn,...
