Simultaneous extraction and enrichment of reactive dye using green emulsion liquid membrane system

Abstract

Currently, an extractive green palm oil-based emulsion liquid membrane (ELM) has been used for simultaneous extraction and enrichment of Reactive Red 3BS from simulated synthetic dye wastewater. The ELM consists of two main phases, which are organic liquid membrane (LM) and stripping solution. During the extraction process, the ELM was dispersed into the simulated synthetic dye wastewater containing the Reactive Red 3BS complexes. The organic LM contains tridodecylamine (TDA), Sorbitan Monooleate (Span 80) and palm oil as a carrier, surfactant and diluent, respectively. The sodium bicarbonate (NaHCO) was used as stripping solution for the enrichment process. Several important parameters that affected the simultaneous extraction and enrichment of Reactive Red 3BS, such as carrier and stripping agent concentrations, extraction time and treat ratio, were investigated. The results showed that almost 90% of Reactive Red 3BS ions were successfully extracted with 10 times enrichment in the stripping phase at the optimum conditions of 0.2 M TDA, 0.1 M NaHCO, 5 min of extraction time and 1:5 of treat ratio. Hence, it can be concluded that palm oil possesses a high potential as green diluent in future technology, especially in ELM process for the removal and recovery of Reactive Red 3BS from synthetic dye wastewater.

Pertraction of Vanadium(V) from Dilute Acidic Media by an Emulsion Liquid Membrane Containing a Commercial Extractant

“…Noah et al applied ELM for recovery of toxic Cr VI from electroplating wastewater and converted it to less toxic Cr III simultaneously through a sustainable continuous ELM extraction system [50]. Application of green diluents such as vegetable oils in ELM formulation is a new area in ELM development that has been recently applied for extraction and enrichment of reactive dyes [51,52].…”

Computational analysis of citric acid pertraction in emulsion liquid membranes

“…Other advantages of this method are its simple operation, low cost and energy consumption, and efficiency for low concentration of solutes. [ 16,17 ]…”

“…According to the authors, both modelling approaches were successful and reasonable results were reported. Othman et al [ 16 ] successfully developed a mathematical model for chromium removal from electroplating wastewater. They used the boundary breakage model considering the emulsion globule approach and the emulsion swelling and breakage during the ELM process, and the derived mass balance for three separated phases, namely, internal, membrane, and feed.…”

Selective Enrichment of Clenbuterol onto Molecularly Imprinted Polymer Microspheres with Tailor-made Structure and Oxygen Functionalities

“…Therefore, enrichment processing plays a vital role in the handling of organic wastes in the analytical fields [7,8]. Adsorption is one of the most commonly used approaches for the enrichment of various contaminants including clenbuterol [9], organic dyes [10], inorganic metal ions [11], etc. [7,12], and many kinds of adsorbents have been explored, such as polymer microspheres [13,14], polymer fibers [15], polymer hydrogels [16], waste biomasses [17], activated carbon [18], carbon nanotubes [19], graphene [20], and silica nanoparticles [21].…”
