Zusammenfassung:	Highlights • Microwave assistance has been employed for the preparation of an effective adsorbent from saw dust. • The adsorbent was successfully employed for the sequestration of dye from aqueous solution. • The quality of the adsorbent was analyzed with characterization techniques. • Langmuir maximum monolayer sorption capacity was calculated as 58.14 mg/g. • Adsorption system was best explained by Freundlich and pseudo-second order models.
