Adsorption Isotherm Studies of Cd(ll) and Pb(ll) Ions from Aqueous Solutions by Bamboo-Based Activated Charcoal and Bamboo Dust

Stevens A. Odoemelam, Francis K. Onwu, Sonde C. Uchechukwu & Mgbeahuruike A. Chinedu · Chemical Science International Journal · 2014

This study investigates a comparative assessment of two adsorbents: Bamboo-based Activated Charcoal (BBAC) and Bamboo dust (BD) in the removal of lead(ll) and cadmium(ll) ions from aqueous solutions. Maximum Pb(II) and Cd(II) removal was observed at pH 6.0. The Langmuir, Freundli...

Biosorption Studies of Cr(VI) Ion from Aqueous Solution using Unmodified and Oxalic Acid Modified African Yam Bean Pod and Groundnut Shell

Humphrey N. Ekeh, Stevens A. Odoemelam & Christopher U. Sonde · International Research Journal of Pure and Applied Chemistry · 2019

This study examines the removal of Cr6+ from aqueous solutions using unmodified and oxalic acid modified African yam bean (AYB) pod and groundnut (G’NUT) shell as adsorbents. The effects of time, pH, temperature, and metal ion concentration were investigated. The amount of metal...
