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... 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) and temperature (298–323 K) on the adsorption process. The optimu ...

... by pyrolysis at 600°C and by physical activation at 600°C in absence of air (AC3). Different activated carbons have been used for the removal of reactive orange (RO) dye from aqueous solutions. Batch adsorption experiments were performed as a function of initial dye concentration, contact time ...

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 th ...

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 it ...
