Continuous Column Study of Chromium (VI) Adsorption by Ion Exchange Resin
Abstract: The Indion GS300 anion exchange resin was trialed for its ability to remove chromium (VI) from synthetic wastewater by continuous column experiments. The ability of Indion GS300 to adsorb chromium (VI) in a fixed-bed column was analyzed. The effects of operating parameters such as flow rate and bed depth on the sorption characteristics of Indion GS300 were investigated. The total adsorbed quantities, equilibrium characteristics were related to the effluent volumes …

A Study on adsorption of Phenol red dye and Chromium (VI) metal ion using activated carbon derived from Lantana camara with the activation of potassium hydroxide.
Abstract: Commercial activated carbons are expensive to produce and regenerate, it is essential to produce activatedcarbon using low-cost raw materials and methods. This study's goal is to demonstrate the possible adsorptionproperties of activated carbon made from Lantana camara for the removal of dyes and metal ions fromaqueous solutions. In this study, activated carbon from Lantana camara stems was obtained through a one-step chemical activation procedure using potassium hydroxide KOH. The surface …

Green Fabrication of Glutaraldehyde-Crosslinked Chitosan/PVA Biocomposite for Heavy Metal Removal from Wastewater
Abstract: Chitosan (CS) and Polyvinyl alcohol (PVA) are polymers that possess biodegradable, biocompatible, and non-toxic properties, making them suitable for wastewater treatment applications. The primary objective of this research is to chemically modify chitosan in a novel manner to enhance its ability to remove hexavalent chromium Cr(VI) from aqueous solutions. In this study, a composite material was synthesized by crosslinking PVA and CS with glutaraldehyde (GA), resulting in the formation of …

Synthesis and Characterization of Bamboo-Supported Nano Zerovalent Iron (NZVI-AB) for Cr(VI) Sequestration
Abstract: Remediation of chromium contaminated sites present both technological and economic challenges, as conventional methods are often too expensive and difficult to operate. In this study, bamboo supported Zero-valent iron (Fe0) nanoparticles were synthesized, characterized, and were tested for removal of Cr(VI). Fe0 nanoparticles were synthesized by the reduction of ferric chloride with avocado polyphenols and characterized by FTIR (Fourier transform infrared) spectroscopy and XRD (X-ray diffraction). Batch experiments were performed …

A Brief Overview of the Removal of Fluoride and Chromium Using Polymer Adsorbents
Abstract: Water tainted with heavy metals are the serious worldwide issues face today because of economic and industrial growth. Even at trace amounts, hexavalent chromium is a significant metal ion pollutant that is highly harmful to humans, animals, plants, and microbes. There are several methods for purifying water, but adsorption is one of the most straightforward, practical, and cost-effective approaches. Chromium is one such significant metal that may be released by …
