Electrokinetic-assisted phytoremediation of atrazine: Differences between electrode and interelectrode soil sections

The combination of phytoremediation and electrokinetics remediation technology on arsenic contaminated remediation in tailing storage facilities from gold mine

“…It can be said that high levels of electromagnetic fields may affect plant uptake ability of elements and nutrients including reducing efficiency of heavy metal contamination to soils. Based on the relationship among the stem, leaf, and root biomass observed in this study, the results were different from those of Sánchez et al. (2019) , who treated atrazine-contaminated soil using EK in conjunction with phytoremediation.…”

“…(2019) , who treated atrazine-contaminated soil using EK in conjunction with phytoremediation. Sánchez et al. (2019) applied an electromagnetic field to plants for 6 consecutive hours for 14 days (alternating between the anode for 4 hours and cathode for 2 hours).…”

A Review on Recent Treatment Technology for Herbicide Atrazine in Contaminated Environment

“…The researchers conducted the atrazine removal experiments with electrokinetic-assisted maize phytoremediation. The results indicated that the combined technology significantly enhanced the accumulation of atrazine in plant tissues when comparing with the phytoremediation process alone, and the total accumulation increased by 20-30% [99]. At the same time, they carried out an electrokinetic-assisted ryegrass (Lolium perenne L.) phytoremediation test; it showed that the total removal of atrazine by ryegrass increased by 7%, with the help of low voltage gradients [100].…”

A mesocosm study of electrokinetic-assisted phytoremediation of atrazine-polluted soils

“…The acid/base buffer capacity of the soil was determined according to the method described by Yeung et al [30]; since the addition of acid or base only changed the soil pH in the range 6-11 [18], it can be said that it possesses a very high acid/base buffer capacity. Ryegrass (Lolium perenne L.) certified seeds were obtained from the Oregon Seed Certification Service (Corvallis, USA).…”

“…Chirakkara et al [15] and Acosta-Santoyo et al [16] applied the combined EKPR technology to a mixed contaminated soil (by heavy metals and polycyclic aromatic hydrocarbons), although they did not find a significant improvement in the removal efficiency as compared to that of phytoremediation experiments. However, we have recently shown that a moderate electric field (1-2 V cm -1 ) can significantly improve the atrazine removal by maize and ryegrass [17][18][19]; Rocha et al [20] have reported an enhancement of removal efficiency and plant biomass by using EKPR with reversal polarity and maize for the treatment of a soil spiked with petroleum. The relevance of the abovementioned results highlights the need to continue studying the application of EKPR to organic pollutants.…”
