Removal of Selenium Oxyanions from Aqueous Solutions by Ion Exchange: Equilibrium, Kinetics, and Mechanistic Modeling
{{output}}
Selenium (Se) is an essential micronutrient but toxic at high concentrations, posing challenges for water treatment. This study investigated the removal of selenate (SeO4 2-) and selenite (SeO3 2-) using the strong-base anion-exchange resin IRA-900, particular... ...
