Lead is a highly toxic heavy metal that creates water pollutant. It can be released from industrial processes, agricultural chemistry, and community wastes, affecting creatures human health even at low concentration. As result, it advised lead removed before releasing wastewater into the environment. This study synthesized three chitosan bead materials shrimp shell wastes which were powder bead...

This article reports on the preparation of iron nanoparticles (FeNPs) supported in chitosan beads (Chi-EDGE-Fe) for removing aldrin from aqueous solutions. The FeNPs and Chi-EDGE-Fe were characterized by means scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), Mössbauer spectroscopy (MS) techniques. TEM, XRD, MS showed that had co...
