Treatment of dye wastewater by in situ hybridization with Mg–Al layered double hydroxides and reuse of dye sludge

Layered Nanomaterials for Environmental Remediation Applications

“…Wei et al studied the adsorption of cationic dye molecules utilizing dye intercalated LDHs. 27 They intercalated multi-anionic dye, DGNL (direct blending scarlet D-GLN), to adsorb cationic dye, victorial blue B, with fairly high capacity of 1024 mg/g, and the adsorption followed Langmuir model. They also suggested that the victorial blue B adsorbed D-GNL/LDH could be re-cycled as polymer colorant.…”

Visible light assisted Fenton-like degradation of Orange II on Ni 3 Fe/Fe 3 O 4 magnetic catalyst prepared from spent FeNi layered double hydroxide

“…Recently, several studies utilized the spent LDHs after treatment of dye effluents as nanofiller or colorant filler for polymer materials, and the results demonstrated to be quite satisfying [6,7]. These studies enlighten us that spent LDHs can be precursors for synthesizing functional materials.…”

Color and Chemical Oxygen Demand (COD) Removal by Bacteria Consortium Using Factorial Design

“…Textile wastewater is a toxic discharge from textile industry, which contains colouring agents that can cause danger to the environment, especially the water bodies such as river, ponds, lakes and sea [20]. Synthetic dyes are widely utilized in textile, paper-made, dyeing and other industries leading to a large-scale development of dye industries [22]. Dyes are most hazardous chemical compound classes found in industrial effluents which need to be treated since their presence in water bodies reduce light penetration, precluding the photosynthesis of aqueous flora [2].…”
