Dissolved humic substances supplied as potential enhancers of Cu, Cd, and Pb adsorption by two different mangrove sediments [PDF]
, 2018 Purpose The external supply of humic substances has been recently suggested for the remediation of metal-polluted sediments; however, little is known about how to supply them and their effects on metal mobility.

Advanced Science, EarlyView.Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Sorption of Neodymium from Nitrate Solutions by Humic Acids-Based Sorbent
Eurasian Chemico-Technological Journal, 2022 This work obtained a sorbent based on humic acids (HA) isolated from oxidized brown coals of the Maikuben deposit. The study of humic acids by IR spectroscopy showed the presence of various functional groups (OH-, COOH-) in the sorbent, which can enter

Humic acid removal by electrocoagulation: characterization of aluminum species and humic acid
Desalination and Water Treatment, 2016 In this study, the different aluminum (Al) species generated during electrocoagulation (EC), the humic acid (HA) removal, and the change in HA characteristics were evaluated. The results show that the distribution of monomeric Al species (Ala), medium polymer Al species (Alb), and colloidal or solid Al species (Alc) was dependent on initial pH and ...

Advanced Science, EarlyView.The 3rd‐generation magnetic super‐stable mineralizer M‐MgAl‐700 features a core‐shell structure, strong superparamagnetism, large surface area, and abundant oxygen defects. It achieves exceptional Cd(II) and As(V) mineralization capacities, reducing both pollutants in co‐contaminated water and soil to meet national standards.

Heavy metal distribution between fractions of humic substances in heavily polluted soils
Plant, Soil and Environment, 2004 Soil organic matter is important in controlling heavy metal behaviour in soils. This study aims to determine the distribution of organically bound Cd, Pb, and Zn between humic and fulvic acids in 20 samples of heavily polluted Fluvisols.
