Lead removal from industrial waste

Abstract

In this study, the heavy metal removal performance of poly(2-hydroxyethyl methacrylate-N-methacryloyl-(L)-histidine methyl ester), poly(HEMA-MAH) cryogel, a known polymer, in HNO3 was investigated. To determine the heavy metal removal performance of cryogel, wastewater was used as obtained from an inorganic material manufacturer. The characterization studies using scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, elemental analysis, waterswelling tests and surface area analysis were conducted. The effect of HNO3 on the adsorption process, especially for metals, was found very effective even in trace amounts.
