Abstract Biobased adsorbents are eco-friendly materials used for water and wastewater treatment and air cleaning. This research work explores the potential use
of rice husk chars as a low-cost adsorbent for pollutants from water, such as
methylene blue and ethinylestradiol. Rice husk chars are prepared by combustion
of rice husks (RH-Char) or pre-treated rice husks (PT-Char). A third char
(M-Char) supplied by a local company which uses rice husks as combustion material is also studied. The chars are characterized by field emission scanning electron
microscopy (FE-SEM) in conjunction with energy dispersive X-ray spectroscopy
(EDX), X-ray powder diffraction (XRD), and zeta-potential measurements.… More >
