“…The extraction percent decreased for concentrations above 10 ppm, this is due to the membrane saturation of the feed phase droplets by MB, and this behavior has also been shown in some studies [22,24]. The optimum extraction percent (98.7%) was achieved for 10 ppm of a dye concentration.…”

In the present work studies were carried out to extract a cationic dye (Methylene Blue MB) from an aqueous solution using emulsion liquid membrane process (ELM). The organic phase (membrane phase) consists of Span 80 as emulsifier, sulfuric acid solution as stripping agent and hexane as diluent. In this study, important factors influencing the extraction of methylene blue dye were studied. These factors include H2SO4 concentration in the stripping phase, agitation speed in the dye permeation stage, Initial dye concentration and diluent type. More than (98%) of Methylene blue dye was extracted at the following conditions: H2SO4 concentration (1.25) M, agitation speed (200) rpm, dye concentration (10) ppm and the diluent type was hexane.

“…Therefore, their removal from industrial effluents has become a major concern. Several methods, including flocculation, coagulation (Verma et al 2012), ion exchange (Greluk and Hubicki 2013), membrane separation (Salima et al 2012;He et al 2008), photodegradation (Kusic et al 2013;Gomez-Solis et al 2012), extraction (Muthuraman et al 2009), chemical oxidation (Turgay et al 2011), biological treatment Turgay et al 2011;Kanagaraj et al 2015), and adsorption (Elemen et al 2012;Chen 2011;Sadhukhan et al 2014;Ozdemir et al 2014) were investigated for dye removal from wastewater.…”

A magnetic iron oxide nanopowder (MnP) prepared by a new combustion technique was characterized and tested as adsorbent for methylene blue (MB) removal from aqueous solution. The effects of pH, adsorbent dose, initial dye concentration, contact time, and temperature on the amount of MB adsorbed were studied. The adsorption kinetics were described by a pseudo-second-order model, and the equilibrium experimental data were well fitted to the Langmuir isotherm, yielding a maximum adsorption capacity of 25.54 mg g -1 . The adsorption mechanism is governed by electrostatic forces and is highly dependent on the pH. The MnP adsorbent demonstrated excellent stability, showing good removal efficiency even after eight cycles of reuse, suggesting its potential large-scale application for the removal and recovery of MB from wastewater.
