PERSULFATE OXIDATlON OF HUMIC ACIDS EXTRACTED FROM THREE DIFFERENT SOILS
Sammary-nree soil humic' aelds were degraded by a new mild chemical oxidatioo me!hod usiog potassium persulfate at pH 2.0. The melbod degraded 30-40"/0 of!he staning material. n. type and relative quantities of tbe products or fragments released as detennined by GC¡MS varíed with the source of lbe polymers. Humic aeld extracted from ao Inceptisol yielded fatty, benzenecarboxylic and pbenolic ae...
متن کاملCopper(II) complexation by humic and fulvic acids from pig slurry and amended and non-amended soils.
The effect of the consecutive annual additions of pig slurry at rates of 0 (control), 90 and 150 m3 ha(-1) y(-1) over a 4-year period on the binding affinity for Cu(II) of soil humic acids (HAs) and fulvic acids (FAs) was investigated in a field plot experiment under semiarid conditions. A ligand potentiometric titration method and a single site model were used for determining the Cu(II) comple...
متن کاملStructural characterization of humic acids, extracted from sewage sludge during composting, by thermochemolysis–gas
Thermochemolysis coupled with gas chromatography and mass spectrometry were applied to determine the structure of humic acids (HA) extracted from a sewage sludge and straw mixture at different steps of composting. The HA extracted from sludge mixture released various compounds, such as mono-, di-, tri-methoxy (alkyl) benzene and (alkyl) benzoic acids, which originated from lignin like derivativ...
متن کاملField dissipation and plant uptake of benzotriazole ultraviolet stabilizers in biosolid-amended soils.
Benzotriazole ultraviolet stabilizers (BUVSs) have been commonly used in industrial and household product formulations, and have been detected in biosolids from wastewater treatment plants. However, little is known about their occurrence and dissipation behavior in the soil environment associated with biosolid application. This study investigated the occurrence and dissipation of five typical B...
متن کاملOccurrence and dissipation of three azole biocides climbazole, clotrimazole and miconazole in biosolid-amended soils.
This study investigated the occurrence and dissipation of three azole biocides climbazole, clotrimazole and miconazole in biosolid-amended soils of the three sites (Zhejiang, Hunan and Shandong) in China following three treatments (CK: control without biosolid application; T1: one biosolid application; T2: biosolid application every year). The results showed that climbazole, clotrimazole and mi...
