Utilization of Labuhan Batu red sand post heavy metals adsorption as sources of high-quality concrete material

South African Journal of Chemical Engineering
Red Sand (RS) is used as an absorbent for heavy metals, then the red sand absorbed by heavy metals is used as a basic material for making concrete. Red sand adsorbed of heavy metals Mn(II), Pb(II), and Zn(II) were 0.39 mg/g, 026 mg/g.

Thermodynamics Approach in the Adsorption of Heavy Metals

, 2011
Adsorción es el término que se utiliza para describir los materiales metálicos u orgánicos que se adhieren a un adsorbente sólido en baja, media y alta cobertura como se muestra en la Figura 1. En donde, el sólido se llama adsorbente, los iones metálicos que se adsorben se llaman adsorbentes, y mientras están unidos a las superficies sólidas se llaman ...

Adsorption of Heavy Metals on Alkali-Activated Zeolite Foams

Materials
Elevated concentrations of heavy metals in natural waters can cause significant ecological problems. It is therefore essential to ensure their removal from any water discharged into the environment immediately, especially in case of an accident, where there is a risk of releasing large quantities or high concentrations. The aim of this paper is to test

Graphene oxides prepared by Hummers’, Hofmann’s, and Staudenmaier’s methods : dramatic influences on heavy-metal-ion adsorption

, 2014
Graphene oxide (GO), an up-and-coming material rich in oxygenated groups, shows much promise in pollution management. GO is synthesised using several synthetic routes, and the adsorption behaviour of GO is investigated to establish its ability to remove ...

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...
