Summary: The release of Cu into water is a significant concern for environmental health. Low-cost adsorbents derived from industrial wastes have been widely studied for Cu(II) adsorption. In this study, ferrochrome ash (FCA) obtained from the baghouse filters of ferrochrome facilities was used for the first time to adsorb Cu(II). The FCA showed potential as an effective adsorbent with a maximum adsorption capacity of 298.75 mg/g, and a pH range of 3-6 was found to be favorable. The adsorption mechanism was determined to be chemisorption involving valency forces between the metal and the adsorbent.

Summary: The adsorbent prepared from Panicum turgidum roots efficiently removes mercury (II) ions from water, with a maximum adsorption capacity of 333.33 mg/g achieved at 30 degrees C. The adsorption process is promoted by the high density of active sites and is independent of the adsorbent surface area. The experimental data fits best with the Freundlich isotherm and pseudo-first-order model. This indicates that Panicum turgidum is a potential adsorbent for wastewater treatment.

Summary: This study investigated the adsorption process of Cu(II) from aqueous solutions using synthetically modified geopolymers under static conditions. Three different geopolymers were used, and their properties were characterized using various techniques. The results showed that the adsorption of Cu(II) by the geopolymers was rapid and increased with increasing metal concentration. The adsorption capacity of the geopolymers was well described by the linear Langmuir isotherm model, and the pseudo-second-order kinetic model was suitable for describing the adsorption behavior.

Summary: The aim of the study was to synthesize zinc oxide nanoparticles (ZnONPs) composite with clay and explore their capability as adsorbents for lead (II) eradication. The Langmuir model was found to be the best for interpreting the adsorption process, with adsorption capacities of 12.43 mg/g and 14.54 mg/g for SC and ZnONPs-SC, respectively. Kinetic studies revealed that pseudo second order kinetics was followed by the processes, indicating multiple steps involved in controlling the rate of reactions.

Summary: This study presents a fast and efficient method using a tree-branched centimetre-scale microfluidic reactor with zinc oxide nanowires (ZnONWs) as a photocatalyst for chemical decontamination of water. The ZnONWs were grown directly on a silicon wafer within the microfluidic chamber, allowing close proximity to the water flow path and reducing interaction time for efficient purification. Characterization of the ZnONWs revealed excellent crystallinity. The microreactor consisted of two dendritic microchannels and a chamber volume of 30 μl, and demonstrated highly effective ibuprofen removal (>99%) in less than 60 seconds.
