Reactive dye

Adsorption of Reactive Blue 21 (RB21) onto fly ash (FA) and sepiolite from aqueous solutions was investigated. Batch adsorption experiments were carried out to evaluate the influences of experimental parameters such as initial dye concentration (100–750 mg/l), pH (2–8), adsorbent dosage (1–4 g/l) an

Reactive dyes are non-degradable and toxic to environments and human being, and their solutions have some color even after wastewater treatment. To remove toxic dyes, adsorption is common choice. In this study, to improve the adsorption capacity, the effect of cationic surfactant was studied to remo

Bagasse pith, which is the main waste from sugarcane industry in Egypt, has been used as a raw material for the preparation of different activated carbons. Activated carbons were prepared from bagasse pith by chemical activation with 28% H3PO4 (AC1), 50% ZnCl2 (AC2) followed by pyrolysis at 600°C an

Micellar-enhanced ultrafiltration (MEUF) was studied to remove reactive dyes from aqueous solution. Two different types of reactive dyes, C.I Reactive Black 5 (RB5) and C.I Reactive Orange 16 (RO16) were tested. A cationic surfactant, cetylpyridinium chloride (CPC) was used for the MEUF and its effe

A combination of adsorption and nanofiltration (NF) was adopted for the treatment of a textile dyehouse effluent containing a mixture of two reactive dyes. The effluent stream was first treated in a batch adsorption process with sawdust as an adsorbent to reduce the dye concentration of the effluent
