Removal of dyes from aqueous solutions using low-cost sorbents made of solid residues from olive-mill wastes (JEFT) and solid residues from refined Jordanian oil shale

Yellow passion-fruit shell as biosorbent to remove Cr(III) and Pb(II) from aqueous solution

“…2) showed that the surface of the biomaterial presents some cavities throughout the surface of the YPFS, indicating that this material presents good characteristics to be employed as a natural adsorbent for metallic ions taken up, as previously reported [29]. SEM photographs were also obtained for YPFS after batch biosorption procedure with Cr(III) and Pb(II).…”

An attractive agro-industrial by-product in environmental cleanup: Dye biosorption potential of untreated olive pomace

“…Therefore, it is chosen as sorbent material in this study. To our knowledge, olive pomace is only used to prepare active carbon as adsorbent to remove methylene blue [10,[15][16][17] and RR22 [18] apart from the degradation of Azo-dye orange (II) [19].…”

Adsorption of Methylene Blue from Aqueous Solutions on a Moroccan Clay

“…The most common adsorbents used for dye removal from wastewater are activated carbons . Natural materials have also been investigated as potential industrial adsorption media. ,,− Regarding the adsorption of dyes using clay minerals, bentonites, montmorillonites, and sepiolites have been described as adsorbents. − …”
