“…Inorganic nanoparticles (nAu, nAg) were analyzed using an ICP-MS type X Series II (Thermo Fisher, Scientific, Breda) in single particles mode with a dwell time of 10 ms. 42–44 The system was calibrated with citrate-capped nAg (20 ng L −1 ) and nAu (51 ng L −1 ) dispersions. The average size of these particles was between 48 and 50 nm (see Fig.…”

“…It typically involves a series of physical, chemical, and biological processes designed to remove or decrease impurities present in the raw water supply prior to further treatment. Pre-treatment has been revealed to be a reliable and effective approach for reducing a wide range of organic micropollutants from surface water (Wu et al 2019b;Timmers et al 2022). In recent years, nano-formulation techniques have been suggested as aspects to minimize the adverse effects of ATZ, where ozonation acts as a binding effect to eliminate recalcitrant organic pollutants in an eco-friendly approach (Kasprzyk-Hordern et al researched.…”

Ozone-based advanced oxidation processes (AOPs) have emerged as promising technologies for water treatment. Recent studies have shown that ozone microbubbles can enhance ozone mass transfer during water treatment, and combining microbubble ozonation with pre-treatment steps can improve the removal of micropollutants from source water. This study evaluated the removal of atrazine from natural water using three different combined processes (chlorine/KMnO4/PAC pre-treatment followed by ozonation). The results indicate that all three combined processes achieved higher atrazine removal rates than pre-treatment alone or ozonation alone. The atrazine removal rate was highest at alkaline pH values, and all three combined processes were affected by oxidant dose and pH. The combination of chlorine pre-treatment with ozonation was the most effective for natural source water, with a removal rate of 59.7% that exceeded the sum of the individual treatments. However, this combined process was affected by water quality, particularly the nature of organic matter, and a relatively high concentration of ammonia nitrogen (greater than 0.5 mg/L) negatively impacted on treatment outcomes. This study highlights the potential for utilizing ozone micro/nanobubbles to enhance ozone mass transfer and provides valuable insights for optimizing the combined application of pre-treatment and ozonation to remove atrazine from natural water sources efficiently.

Industrial wastewater polluted with high concentrations of Cr is commonly discharged into water resources without proper treatment. This gives rise to the deterioration of water quality and imposes adverse effects on public health. Therefore, this study is aimed at removing Cr from electroplating wastewater using activated carbon produced from water hyacinth under a full factorial experimental design with three factors and three levels (pH,2,5 and 8, adsorbent dose 0.5,1and1.5 in 100 mL and contact time 30, 60 and120 min). A phosphoric acid solution of 37% was used to activate the carbon, which was then subjected to thermal decomposition for 15 min at 500 °C. The activated carbon was characterized by the presence of a high surface area (203.83 m2/g) of BET, cracking of adsorbent beads of SEM morphology, amorphous nature of XRD, and many functional groups of FTIR such as hydroxyl (3283 cm−1), alkane (2920 cm−1), nitrile (2114 cm−1) and aromatics (1613 cm−1). The minimum Cr adsorption performance of 15.6% was obtained whereas maximum removal of 90.4% was recorded at the experimental condition of pH 2, adsorbent dose of 1.5 g/100 mL, and contact time of 120 min at a fixed value of initial Cr concentration of 100 mg/L. Similarly, the maximum Cr removal from real electroplating wastewater was 81.2% at this optimum point. Langmuir's model best described the experimental value at R2 0.96 which implies the adsorption is chemically bonded, homogeneous, and monolayer. Pseudo-second-order model best fits with the experimental data with R2 value of 0.99. The adsorbent was regenerated for seven cycles and the removal efficiency decreased from 93.25% to 21.35%. Finally, this technology is promising to be scaled up to an industrial level.
