Organic removal from coal-to-chemical brine by a multistage system of adsorption-regeneration and electrochemically driven UV/chlorine processes

Adsorption and desorption behavior of Zn2+ in a flow-through electrosorption reactor

“…As Figure 9 B shows, the first-order derivative of the equation achieves zero between 239 and 240, and the adsorption efficiency does not decrease indefinitely during the adsorption cycle and eventually stabilizes at about 75% of the initial adsorption efficiency. 45 , 46 The removal of Zn from wastewater by flow-through electroabsorption has certain practical significance, and its application effect in practical engineering can be investigated.…”

Highly coordinated Fe–N5 sites effectively promoted peroxymonosulfate activation for degradation of 4-chlorophenol

“…Advanced oxidation processes (AOPs) have emerged as effective technologies to generate a broad range of reactive oxygen species (ROS) for efficiently degrading a variety of refractory contaminants, making AOPs a promising option for wastewater treatment. 1–5 Peroxymonosulfate (PMS)-based AOPs have recently attracted extensive attention due to their advantages, which include enhanced reaction rates, more robust oxidation capacity, and relatively simpler operation. 6 Moreover, PMS-based AOP studies have reported organic contaminants decomposing into low or non-toxic substances and even completely mineralizing into carbon dioxide (CO 2 ) and water (H 2 O).…”
