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

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.

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation
Advanced Materials, EarlyView.Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...
