Investigating the effect of degree of compaction, initial water content, and electric field intensity on electrokinetic remediation of an artificially Cu- and Pb-contaminated loess

Wenle Hu et al.

Summary: With the rich copper and lead mineral deposits and high production in North-Western China, the metallurgical industry has achieved prosperity. However, the metallurgical industrial waste containing heavy metals can cause contamination and pose a threat to the fragile loess environment. Electrokinetic (EK) technology, due to its high efficiency and low risk of secondary pollution, is becoming a popular alternative for remediating contaminated soil. This study investigates the impact of compaction, initial water content, and electric field intensity on the removal of heavy metals in loess. The experimental results show that lower compaction, higher initial water content, and higher electric field intensity can enhance the removal of heavy metals, but the precipitation of heavy metal compounds at the cathode can also deteriorate the removal efficiency. Dynamic pH regulation and the use of a permeable reactive barrier are considered necessary for optimizing heavy metal removal in loess.

Ion rejection performances of functionalized porous graphene nanomembranes for wastewater purification: A molecular dynamics simulation study

Ehsan Tabasi et al.

Summary: The performances of small- and large-pore porous graphene nanomembranes (PGNMs), both pristine and functionalized, were investigated for the purification of heavy metal ions and nitrate-contaminated wastewater using molecular dynamics simulation. The results showed that functionalized PGNMs with large pores had higher water flow rates. The amide-functionalized PGNM exhibited the highest flow rate, and the small-pore PGNMs achieved 100% rejection of Cu2+ and As3+ ions. The rejection level of NO3- ions was approximately 95%. For large-pore PGNMs, As3+ ions were completely rejected, while a few Cu2+ and NO3- ions passed through the pores with no significant dependence on the graphene surface chemistry.

Potassium permanganate modification of hydrochar enhances sorption of Pb(II), Cu(II), and Cd(II)

Yue Zhang et al.

Summary: Hydrochars derived from hydrothermal carbonization of hickory wood, bamboo, and wheat straw were modified with potassium permanganate for effective sorption of heavy metals. The modified wheat straw hydrochar (WSHyC-0.2KMnO(4)) exhibited the highest adsorption capacity, attributed to its large specific surface area, abundant surface oxygenic functional groups, and significant presence of MnOx microparticles. Batch adsorption experiments demonstrated that WSHyC-0.2KMnO(4) had a faster adsorption rate and much higher adsorption capacity (12-17 times) for Pb(II), Cd(II), and Cu(II) compared to WSHyC, due to increased OCFG and MnOx microparticles on its surface facilitating ion exchange, electrostatic interactions, and complexation mechanisms.

Effects of channel size, wall wettability, and electric field strength on ion removal from water in nanochannels

Filippos Sofos et al.

Summary: Molecular dynamics simulations are used to investigate the impact of nanopore size, wall wettability, and external electric field strength on ion removal from water solutions. The results show that the presence of ions and the influence of external electric field create a multivariate environment that affects fluidic interactions and ion drift. Electric field strength is the primary factor in ion separation, while wall wettability has minimal impact. Furthermore, diffusion coefficients decrease with increasing external electric field and are not affected by wall wettability.
