Design of A New Bead Injection System for Removal Methylene Blue using Nanoparticale Derivative from Selenium(IV) Compound

Abstract

    This research included a study of a new  bead injection system design for removing methylene blue dye using selenium nanoparticles at a wavelength of 664 nm. The optimum conditions  pH, flow rate, dye volume, and selenium nanoparticle mass were studied and determined. Were  7 ,10 ml/min , 0.157 ml and 0.004 g respectively . The calibration curve was prepared and the linearity range was from (0.5-25) mg/L and the Sandell's  sensitivity was = 8.695 × . The dispersion coefficient and repeatability were also studied, which were  2.383 , 10 reading respectively , and it was found that the proposed method gave good results with a recovery rate of ( 99.879 % -100.064% ).
