In this paper, the ability of waste biomass as an adsorbent was investigated. Oat straw was chosen as the starting raw material. In order to improve the adsorption capacity this material was modified with selected deep eutectic solvent (DES). Changes in the structure of the native and modified samples were examined using the SEM analysis. The efficiency of the adsorption of heavy metal ions from a multimetal solution was tested on the modified oat straw. The maximum obtained capacities of lead, copper and zinc ions were 77mg/g, 29.5mg/g and 44.1mg/g, respectively. The obtained results showed that adsorption follows pseudo-second-order kinetics model that imply chemisorption as a rate controlling step.
