Sorption of Neodymium from Nitrate Solutions by Humic Acids-Based Sorbent
نویسندگان
چکیده
This work obtained a sorbent based on humic acids (HA) isolated from oxidized brown coals of the Maikuben deposit. The study by IR spectroscopy showed presence various functional groups (OH-, COOH-) in sorbent, which can enter into ion-exchange reactions with metals. Humic have been tested as for neodymium. Neodymium sorption was carried out under static conditions nitrate solutions. It found that time 30 min and solution pH is 1.0, efficiency neodymium 95.5%. A used to separate dissolving electronic waste (neodymium magnet). SEM-analysis mapping surface after absent surface.

Phenanthrene sorption to structurally modified humic acids.
Several studies emphasize the importance of soil organic matter characteristics in hydrophobic contaminant sorption and outline the strong dependence of sorption on organic matter aromaticity. In this study, the role of organic matter aromaticity in phenanthrene sorption was investigated using humic acids (HAs) from compost, peat, and soil that were structurally modified by bleaching, hydrolysi...
متن کاملHumic acid removal from aqueous solutions by peroxi-electrocoagulation process
Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...
متن کاملTetracycline sorption to coal and soil humic acids: an examination of humic structural heterogeneity.
The sorption properties of tetracycline were compared between a coal humic acid (CHA) and a soil humic acid (SHA) under various solution chemistry conditions. Structural characteristics of the two humic acids were quantified in detail by elemental analysis, solid-state (13)C nuclear magnetic resonance (NMR), acid-base titration, and Zeta potential measurement. The CHA consists primarily of poly...
