Summary: This study investigated the potential use of Neolamarckia cadamba as nanofibrillated cellulose (NFC) filter paper for treating industrial textile wastewater. Experimental results showed that at pH 6.5, with 100% initial feed concentration of the textile wastewater and a 60:40 cellulose dosage ratio, the NFC filter paper achieved a high colour removal efficiency and an optimum normalized flux. The study also provided insights into the operating parameters of filter papers for optimal performance.

Summary: This study aimed to remove Methylene blue (MB) from textile wastewater using activated carbon developed from Rumexabyssinicus. The activated carbon was characterized and the adsorption isotherm and kinetics were investigated. Optimization of MB dye removal was carried out and the maximum removal efficiency of 99.9% was achieved at optimum conditions. The Freundlich isotherm model and pseudo-second-order kinetics were found to be the best fit for the adsorption process, indicating its potential for industrial use.

Summary: In this study, nanoscale photocatalysts were synthesized and evaluated for the simultaneous detoxification of toxic Sb(III) and adsorption of less toxic Sb(V). The TiO2-in-CNT system exhibited high efficiency in removing Sb(III) under solar irradiation, while the TiO2-out-CNT system utilized HO· to facilitate the conversion of Sb(III). Additionally, the TiO2-in-CNT system showed faster removal kinetics and good selectivity and performance in different water matrices.

Summary: The co-existence of heavy metals and organics in industrial effluents poses potential health risks and ecological harm, necessitating the simultaneous removal of these pollutants. Technologies such as adsorption, ion exchange, photo-catalysis, and coagulation have been used for this purpose, with their success dependent on water matrices and treatment media. This review critically examines the advantages, limitations, and mathematical modeling of these technologies for concurrent removal of organics and heavy metals in contaminated systems.
