Electrochemical Analysis and Applications

Adsorption is important for treating water and effluents containing disposed dyes, particularly due to their intense industrial use. Extensive research in literature has focused on how to remove yellow tartrazine (TAR). Therefore, this study aims to describe TAR adsorbents, including materials, their efficiency, and kinetic parameters. To achieve this, studies published between January 2012 and January 2023 were selected. Among the TAR adsorbents, noteworthy options are chitosan- and chitin-based materials, synthetic materials, agro-industrial residues, activated carbon, nanoparticles, among others. Chitosan exhibited the highest adsorption capacity, although some types of activated carbon and nanocomposites also proved to be very efficient. Generally, TAR adsorption was most effective at pH 2.0. Majority of studies indicated favorable results using Langmuir and Freundlich's isotherm models, along with mathematical pseudo-second-order models. Thus, adsorption demonstrates its capability to remove TAR from water and effluents, but ongoing research should focus on developing even more efficient and sustainable adsorbents.
