    reaction. Ammonia solution, 10 mL of 33 % NH4OH diluted by 20 mL of distilled water, was added drop wisely until a deep brown precipitate was produced. The filtered precipitate (EB) was washed with sufficient amount of deionized water then washed by ethanol to remove residual oxidant, unreacted monomer and oligomer until the filtrate became colorless and oven dried at 60 °C for overnight. The deep brown dried powder produces PANI-AA-o-PDA (PAAAPDAK1). The gained terpolymer yield was calculated…

    volumetric flask and 50 ml methanol was added to it and shakes for few minutes to prepare 1000microgram/ml. Stock solution From this solution the stock solution was prepared by taking 1 ml from standard solution and made the volume to 100 by ethanol and then prepare the solution of 0-10 µg/ml and check the absorbance at 330 nm in UV spectrum. Absorbance v/s concentration were plotted to obtain the calibration graph. The drugs obeyed beer’s law with the above concentration range with ‘r’…
