Eureka lemon, ethanol (C₂H₅OH, Sigma Aldrich, Darmstadt, Germany), and dichloromethane (CH₂Cl₂, Merck, Darmstadt, Germany) were used to synthesize CQD solution. Silver nitrate (AgNO₃, Sigma Aldrich) and sodium borohydride (NaBH₄, Sigma Aldrich) were utilized for the synthesis of pure Ag and Ag/CQD nanomaterial. Tartrazine (Dye content ≥ 85%, Sigma Aldrich) was used as the dye pollutant. Besides, sodium hypochlorite (NaOCl, Sigma Aldrich) was applied as membrane cleaning agent. Polysulfone (PSF, Solvay, GA, USA), polyvinylpyrrolidone (PVP, 160,000 g/mol, Sigma Aldrich) and N-methyl-2-pyrrolidone (NMP, Merck) were used for the fabrication of composite membrane.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
