Evaluation of soil washing process with carboxymethyl-β-cyclodextrin and carboxymethyl chitosan for recovery of PAHs/heavy metals/fluorine from metallurgic plant...
(Elsevier, 2014-08-01)
Abstract Polycyclic aromatic hydrocarbons (PAHs)/heavy metals/fluorine (F) mixed-
contaminated sites caused by abandoned metallurgic plants are receiving wide attention. To
address the associated environmental problems, ...
Evaluation of enhanced soil washing process and phytoremediation with maize oil, carboxymethyl-β-cyclodextrin, and vetiver grass for the recovery of organochlorin...
(Academic Press, 2014-08-01)
Abstract An innovative ex situ soil washing technology was developed in this study to
remediate organochlorine pesticides (OCPs) and heavy metals in a mixed contaminated
site. Elevated temperature (60 C) combined with ...
Enhanced soil washing process for the remediation of PBDEs/Pb/Cd-contaminated electronic waste site with carboxymethyl chitosan in a sunflower oil–water solven...
(2015-02-01)
Abstract An innovative ex situ soil washing technology was developed to remediate
polybrominated diphenyl ethers (PBDEs) and heavy metals in an electronic waste site.
Elevated temperature (50° C) in combination with ...
Role of cosubstrate and bioaccessibility played in the enhanced anaerobic biodegradation of organochlorine pesticides (OCPs) in a paddy soil by nitrate and methyl...
(Springer Berlin Heidelberg, 2014-07-01)
Abstract The present study was conducted to investigate the anaerobic biodegradation
potential of biostimulation by nitrate (KNO 3) and methyl-β-cyclodextrin (MCD) addition on
an aged organochlorine pesticide ...
Remediation of organochlorine pesticides (OCPs) contaminated site by successive methyl-β-cyclodextrin (MCD) and sunflower oil enhanced soil washing–portulaca...
(Pergamon, 2014-06-30)
An innovative ex situ soil washing technology was developed in this study to
remediate organochlorine pesticides (OCPs)-contaminated site. Elevated temperature (50
C) combined with ultrasonication (35 kHz, 30 min) at ...
Tenax extraction for exploring rate-limiting factors in methyl-β-cyclodextrin enhanced anaerobic biodegradation of PAHs under denitrifying conditions in a red paddy...
(Elsevier, 2014-01-15)
The effectiveness of anaerobic bioremediation systems for PAH-contaminated soil
may be constrained by low contaminants bioaccessibility due to limited aqueous solubility
and lack of suitable electron acceptors. Information ...
Response surface methodology to understand the anaerobic biodegradation of organochlorine pesticides (OCPs) in contaminated soil—significance of nitrate conce...
(2014-09-01)
Abstract Purpose Problems associated with Organochlorine pesticide (OCP)-contaminated
soils have received wide attention. To understand the anaerobic biodegradation process
constraints, innovative mathematical analysis ...
Isolation and characterization of a toxic metal-tolerant Phenanthrene-degrader Sphingobium sp. in a two-liquid-phase partitioning bioreactor (TPPB)
(2013-10-01)
A phenanthrene-degrading strain PHE3, identified as the genus of Sphingobium,
was isolated using a two-liquid-phase partitioning bioreactor. More than 96% of the initial
amount (up to 100 mg l− 1 silicone oil) of ...
Does powder and granular activated carbon perform equally in immobilizing chlorobenzenes in soil?
(Royal Society of Chemistry, 2015)
The objective of this study is to compare the efficacies of powder activated carbon (PAC) and
granular activated carbon (GAC) as amendments for the immobilization of volatile
compounds in soil. Soil artificially-spiked ...
Effects of pH and metal ions on oxytetracycline sorption to maize-straw-derived biochar
(Elsevier, 2013-05-30)
Biochars produced from biomass residues have been recognized as effective sorbents to
hydrophobic compounds, but knowledge on sorption of antibiotics to biochar and its
mechanisms are still inadequate. Sorption of ...
