In order to study the mechanism of increasing bioavailability of ferrous iron (Fe 2+) combined with ethylenediaminetetraacetic acid (EDTA) in the process of biogas production by anaerobic fermentation, three groups of simulated coal seam biogas production experiments were set up with raw coal, raw coal + Fe 2+, and raw coal + Fe …

The production of biogas by anaerobic digestion from organic materials is a well-investigated and well-established process. ... Trace elements essential for the growth and metabolism of the methanogens are iron, nickel, cobalt ... This shows that the addition of EDTA to the biogas process also increased the stability of the process, not only ...

precipitation, ethylenediaminetetraacetic acid (EDTA) is used as a stabilizing agent to prevent iron and phosphorus co-precipitation. This process can be operated as a closed loop, allowing the recovery and recycling of both water and EDTA, while eliminating the production of liquid waste. The developed

In this work, EDTA (Ethylene diamine tetraacetic acid) was employed as a chelating agent of iron ions, which simultaneously changed the redox property of coordinated iron. The Fe 2+-EDTA complexes in the presence of dissolved oxygen enabled the two-electron transfer from Fe 2+ to O 2 and the in-situ production of H 2 O 2, which …

The intensity of the group D was weaker in the "plasma + iron" system than in the plasma system. These results suggested that Cu-EDTA structures were destroyed by the plasma oxidation, and some byproducts were generated; the presence of iron powder could intensify Cu-EDTA decomplexation and decomposition process of byproducts …

3.1.3 Manufacturing process. The applicant provided description of the manufacturing process for the novel food ingredient. The product under assessment is obtained by crystallisation following the addition of an aqueous solution of FeCl 3 to an aqueous solution of tetrasodium EDTA (Documentation provided to EFSA n. 1).

Ethylene Diamine Tetraacetic Acid Plant (EDTA) Ethylenediaminetetraacetic acid (EDTA) is a chelator of metal ions. It is a substituted diamine, which has antibacterial activity. EDTA removes the …

EDTA is a recoverable and reusable chelating agent with great potential. It is also the most efficient complexing agent used for phytoremediation of heavy metal contaminated soils, as it increases the bioavailability and plant uptake of metals in the soil [13]. The use of EDTA in the biogas process is currently not a common practice.

Fe(II)-EDTA would not existed as the dominant species, but quickly oxidized to Fe(III)-EDTA considering the fast kinetics (k obs = ∼0.5 s −1 at pH 7) (Zang and Van Eldik, 1990).Nevertheless, the anoxic EC process did not cause significant abatement of EDTA, as 93 % EDTA still presented as Fe(III)-EDTA in the solution (Fig. 1 a).Then the …
