Adsorption of anionic dyes on spent tea leaves modified with polyethyleneimine (PEI-STL)
This paper investigates the adsorption performance of spent tea leaves (STL) modified with polyethylenimine (PEI) on two anionic dyes, namely Reactive Black 5 (RB5) and Methyl Orange (MO), from simulated wastewater. Modification of STL surface with PEI reduced the STL surface area. Abundant basic gr...
