Intensification of the sorption of Rhodamine B from aqueous phase by loquat seeds using ultrasound

► The feasibility of using loquat seeds for the sorption of Rhodamine B was investigated. ► Batch sorption studies were conducted in the absence and presence of ultrasound. ► The sorption of dye was drastically improved in the presence of ultrasound. ► Coupling of ultrasound and stirring for the sorption process was shown to be of interest.
