摘要: Abstract In this study, a new application of polypyrrole (PPy) synthesized chemically in presence ferric chloride as an oxidant coated on rice husk ash (RHA) by oxidative chemical polymerization method is used, has been found to be the and water reported best solvent for pyrrole. The removal anions, heavy metals such copper, iron zinc COD (chemical oxygen demand) from textile wastewater using completely mixed batch reactor (CMBR) technique investigated when its blend nanocomposites with were used. Experiments done PPy/RHA during 30 min 5 min intervals. It observed that increasing time (5–20 min) efficiency increased but, after 20 min did not increase significantly. can concluded RHA composites does play significant role anions but considerable it causes composites. Besides, morphology was tested scanning electron microscopy (SEM) characterize surface PPy at very high magnification accelerating voltage 15 kV, structure Fourier Transform Infrared spectroscopy (FTIR) wavelength range 400–4000 cm −1 , respectively. used effective adsorbent wastewater.
