Paddle-Wheel-Shaped Porous Cu(II)–Organic Framework with Two Different Channels as an Absorbent for Methylene Blue

“…Industrial wastewater discharges contribute to the continuous degradation of the aquatic environment as social industry advances. − However, after being released into the environment untreated, the wastewater containing dyes is highly poisonous and carcinogenic, which poses a serious threat to human life. − Since dyes are difficult to dissolve under natural circumstances, dye wastewater treatment is a very important research field at present. Methylene blue (MB) belongs to thiazine dyes and is a cationic compound. − It causes not only the death of a large number of aquatic animals but also seriously pollutes water and destroys the ecological environment when the dye concentration increases to a certain extent. − At present, there are different methods to remove dyes from the wastewater, including the adsorption method, − membrane separation method, − electrochemical method, , photocatalytic method, , biodegradation method, and so forth. − Among them, the adsorption method is widely used to treat dyes in wastewater because of its advantages, including simplicity of use, environmental protection, and accessibility. Meanwhile, the adsorbent can be specifically chosen or created in accordance with the characteristics of adsorbed substances .…”

“…8−10 It causes not only the death of a large number of aquatic animals but also seriously pollutes water and destroys the ecological environment when the dye concentration increases to a certain extent. 11−14 At present, there are different methods to remove dyes from the wastewater, including the adsorption method, 15−19 membrane separation method, 20−23 electrochemical method, 24,25 photocatalytic method, 26,27 biodegradation method, and so forth. 28−30 Among them, the adsorption method is widely used to treat dyes in wastewater because of its advantages, including simplicity of use, environmental protection, and accessibility.…”
