Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 766-84-7, Name is 3-Chlorobenzonitrile, molecular formula is C7H4ClN, belongs to nitriles-buliding-blocks compound. In a document, author is Morshed, Mainul, introduce the new discover, COA of Formula: C7H4ClN.
Poly-2-amino-benzonitrile, a wide dynamic pH linear responding material
In this paper, poly-2-Aminobenzonitrile (PABN), might be thinking as a functionalized polyaniline (PANI), is prepared and its application in the potentiometric pH sensor is demonstrated. The obtained PABN is characterized by FTIR, UV-Vis Spectra, XPS, SEM, BET surface area analysis, and BJH pore size and volume analysis. The pH sensors are characterized by an open circuit potential method with the two-electrode system. The experimental results demonstrate that the potentiometric pH sensors have the near Nernstian sensitivity of -52 mV/pH in the wide range of pH 1 to 13 in phosphate buffers. Prepared pH electrode has significantly lower potential deviation, fluctuation, drift, and hysteresis in sensitivity performances and proved to be the useful one for practical application with long-time stability and repeatability. Ion selectivity tests demonstrate the promising ion-selective electrode of PABN. This idea might be helpful to design functional polymers that have wide range of corresponding properties.
