Rapid removal of lead (II) ions from aqueous solutions by saffron flower waste as a green biosorbent

In this work for the first time Saffron flower waste as a low cost and green adsorbent for removal of lead toxic ions from aqueous solution by shaking and ultrasonic waves is reported. Properties of this natural absorbent are characterized by scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR) and energy dispersive X-ray diffraction (EDX). The specific surface area of the saffron flower waste is measured via...
