Application of a phosphonium-based ionic liquid for reactive textile dye removal: Extraction study and toxicological evaluation

Separation of Anionic Chlorinated Dyes from Polluted Aqueous Streams Using Ionic Liquids and Their Subsequent Recycling

“…On the other hand, the separation processes offer the isolation of dyes from wastewater streams. Thus, the separation processes include adsorption [15], membrane processes [16] or innovative methods of extraction [17][18][19][20][21][22][23][24].…”

“…Some authors [17][18][19][20][21][22][23][24] reported the application of ILs in the extraction of acid dyes from aqueous solutions. Vijayaraghavan et al [17], for the first time in 2006, reported on the effective extraction of selected acid azo dyes from leather industry wastewater using ILs.…”

“…Vijayaraghavan et al [17], for the first time in 2006, reported on the effective extraction of selected acid azo dyes from leather industry wastewater using ILs. Since 2006, other authors [18][19][20][21][22][23][24] introduced efficient methods of acid dyes extraction using ILs. Different types of ILs were tested, such as imidazolium based ILs [18][19][20]22] or phosphonium based ILs [17,23,24].…”

Different types of ILs were tested, such as imidazolium based ILs [18][19][20]22] or phosphonium based ILs [17,23,24]. The extraction efficiency can be also dependent on the structure of ILs and/or dyes [17][18][19][20][21][22][23][24].…”

“…Different types of ILs were tested, such as imidazolium based ILs [18][19][20]22] or phosphonium based ILs [17,23,24]. The extraction efficiency can be also dependent on the structure of ILs and/or dyes [17][18][19][20][21][22][23][24]. However, most of the published works are associated with high doses of ILs necessary for the effective extraction of acid dyes [17][18][19][20][21][22][23].…”
