Biosorption of aqueous Pb(II) by H3PO4-activated biochar prepared from palm kernel shells (PKS)

Autor: Wipawee Dechapanya, Attaso Khamwichit

Publikováno v: Heliyon, Vol 9, Iss 7, Pp e17250- (2023)

The conversion of palm kernel shells (PKS), a major agricultural waste from the palm oil sector, into a potentially high-value biosorbent for heavy metals-contaminated wastewater treatments was explored in this work. Following carbonization, the acti

Swift Removal of the Heavy Metals Cadmium and Lead from an Aqueous Solution by a CAN-Zeolite Synthesized from Natural Clay

Autor: Lobna Aloui, Soumaya Mezghich, Lamjed Mansour, Sana Hraiech, Fadhila Ayari

Publikováno v: ChemEngineering, Vol 7, Iss 6, p 113 (2023)

CAN-zeolite was synthesized with a high purity from natural kaolinite via alkali fusion by hydrothermal treatment at a pressure of 1 kbar H2O. It was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy

Removal of Congo red dye and Cd(II) and Fe(III) ions from aqueous solution using clay minerals: Equilibrium adsorption studies

Autor: Y. M. L. Chathurangani, K. Masilamani

Publikováno v: Ceylon Journal of Science, Vol 50, Iss 4, Pp 533-540 (2021)

This study was performed to assess the removal of dyes and heavy metals from wastewater using locally available natural clays. Modifications of two different local raw clays were carried out by acid activation. The characterization of the raw clay an
