Abstract:This manuscript reports the purification of wastewater from Congo red (CR) by adsorbing it on sawdust of Pinus walichiana (PW) and Populus ciliata (PC) used as adsorbents. The adsorbents were characterized by Field emission scanning electron microscopy (FESEM), Energy dispersive X‐rays (EDX) spectroscopy, X‐rays diffraction (XRD) and BET surface area and pore size analysis. Different adsorption models like Langmuir, Temkin, Freundlich and Dubinin‐Radushkevich (R‐D) were applied to the system. The adsorption of… Show more
