Effect of wood vinegar on adsorption and desorption of four kinds of heavy (loid) metals adsorbents
SUN Shuang, GAO Zi-Ting, LI Zhan-Chao… - Chinese Journal of …, 2020 - Elsevier
Wood vinegar (WV) is a common agricultural additive used for treatment of soil and
stimulation of plant growth. Phosphate rock powder (PR), coal fly ash (CFA), zeolite (ZE) and
bentonite (BE) are the common adsorbents for heavy (loid) metals (HMLs)-contaminated soil
treatment. The present study focused on the effect of desorption of Pb (II), Cd (II) and As (III)
from adsorbents in the presence of WV. The experimental results revealed that the removal
fractions of HMLs from adsorbents gradually decreased and then remained steady with the …
