Removal of cyanocobalamine from aqueous solution using mesoporous activated carbon

Adsorption of anionic and cationic dyes by activated carbons, PVA hydrogels, and PVA/AC composite

“…Removal of these compounds is important for solving both medical and environmental protection problems [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. This capability is also dependent on the accessibility of adsorbent pores, and is especially relevant for composite materials where polymer coverage of adsorbent particles occurs.…”

Removal of methylene blue dye from aqueous solution by activated carbon prepared from cashew nut shell as a new low-cost adsorbent

“…This is attributed to its low cost, easy availability, simplicity of design, high efficiency, easy operation, biodegradability and ability to treat dyes in more concentrated forms [7,8]. Activated carbon adsorption is one such method which has a great potential for the removal of dyes from wastewater [9][10][11][12][13][14]. Commercially available activated carbons are usually derived from natural materials such as wood or coal and still considered expensive [15].…”

Décoloration des effluents par des structures adsorbantes générées par électrocoagulation avec des électrodes d’aluminium et de fer

“…Le rejet dans les eaux naturelles de ces effluents fortement colorés de ces industries peut causer des dommages sévères à l'environnement (AkSU et TEzER, 2001). Les colorants peuvent notamment causer des dermatites et des irritations de la peau et certains sont cancérigènes et mutagènes pour les organismes aquatiques (LORENC-GRABOwSkA et GRyGLEwiCz, 2007;MATHUR et al, 2006 GHAzi et al, 2004;TORRADES et al, 2004), la séparation membranaire telle que la microfiltration, l'ultrafiltration, la nanofiltration (MUTLU et al, 2002), l'electro-Fenton (ÖzCAN et al, 2008ÖzCAN et al, 2009), traitement biologique anaérobie (DOS SANTOS et al, 2007;FRANk et al, 2005).…”
