Application of A New Polymer Agcl Nanoparticles Coated Polyethylene Terephetalat [Pet] As Adsorbent For Removal and Electrochemical Determination of Methylene Blue Dye

In this study, two efficient applications for a novel modified polymer (polyethylene terephthalate [pet] modified with agcl nanoparticles) were proposed and experimentally evaluated. first, pet-agcl nps were applied as an adsorbent to remove methylene blue (mb) dye, and the effect of ph, incubation time, concentration of mb, and temperature on the dye removal were studied and optimized to improve dye removal efficiency. the optimum condition included ph 9, temperature 45 ⁰c, and incubation time 24 h. the adsorption fitted the temkin isotherm model. in the other part of the study, a composite of pet-agcl nps with multiwall carbon nanotubes (mwcnts) was used to modify the gold electrode in order to detect mb dye. the modified electrode exhibited a linear detection range, 5 μm to 10 nm, with a detection limit of 4.6 nm.
