Metakaolins (MKs) prepared from low-grade kaolins located in the Alvarães (A) and Barqueiros (B) regions of Portugal were used as aluminosilicate source to compare their effect on compressive strength heavy metal adsorption geopolymers. Natural zeolite, an inexpensive, efficient adsorbent, was additive formulations enhance geopolymers’ capacities reduce MK utilization’s environmental footprint....

contamination of water by heavy metals is a global problem. nowadays everybody knows that heavy metal ions consist of iron, lead, manganese, zinc, copper, cadmium, and nickel and so on they are common contaminants in wastewater and known to be toxic and carcinogenic that lead to many problems for human and water environment. in this research, experiments have been performed in the batch system ...

Agricultural by-products, such as peanut shells, contribute large quantities of lignocellulosic waste to the environment each growing season; but few, if any, value-added uses exist for their disposal. The objective of this study was to convert peanut shells to activated carbons for use in adsorption of select metal ions, namely, cadmium (Cd2+), copper (Cu2+), lead (Pb2+), nickel (Ni2+) and zin...

The textile industry produces enormous volumes of wastewater which must be treated effectively. In this study, biosorbent from the agricultural waste potato peels (PP), is environmentally friendly and easy to find everywhere, was used for treatment real wastewater. Physical modification, chemical activation, bio-hybrid high-pressure modification processes were applied PP investigate organic pol...

Heavy metals are hazardous to health at certain levels. Currently, heavy removed by physicochemical treatments, such as adsorption, flotation, and electrochemical deposition, also biological algal biofilm reactor anaerobic ammonium oxidation. In this study, magnetic biochar was produced enhance the effectiveness performance of adsorbent for metal removal. This study aimed synthesise high-perfor...
