Case Study

Acid Yellow 49 for Preparation of Intercalated Layered Double Hydroxide Films

Tang, Pinggui, et al.Dyes and Pigments, 2011, 91(2), 120-125.

Layered double hydroxide (LDH) materials have anion exchange capabilities and composition flexibility, and are often studied as flame retardants, catalysts, and adsorbents. By embedding dye anions into the interlayer channels of LDHs films, colored functional films with excellent thermal stability and light resistance can be synthesized. For example, acid yellow 49 (4-[2-(5-amino-3-methyl-1-phenyl-1H-pyrazol-4-yl)diazenyl]-2,5-dichlorobenzenesulfonic acid, abbreviated as PPDB) can be embedded in the pores of the LDHs film, which can improve its thermal stability and light resistance, thereby preparing a yellow coating film with excellent thermal stability and light resistance.
Preparation of ZnAl-PPDB-LDH/alumina/aluminum film
· The PPDB anion intercalated film was prepared by the ion exchange method using the ZnAl-NO3-LDH/alumina/aluminum film as a precursor.
· The precursor film was immersed in the solution of PPDB (0.1 M, 100 mL) in a sealed beaker and maintained at 100 °C for 2.5 h.
· The film was then removed and rinsed five times with hot water and subsequently dried at 100 °C for 12 h.

Electrochemical Degradation of Acid Yellow 49 in Flow Reactor

Wächter N, et al. International Journal of Electrochemical Science, 2015, 10(2), 1361-1371.

Acid yellow 49 is a bright yellow azo dye widely used for dyeing fabrics and leather. Electrochemical oxidative degradation strategy has been applied for the removal of acid yellow 49. Using boron-doped diamond (BDD) as the anode, the acid yellow 49 dye can be effectively decolorized at a current density of only 5 mA cm-2.
Electrochemical degradation of acid yellow 49
· Electrochemical degradation experiments were performed in a flow electrochemical system with a filter-press reactor. Before each degradation experiment, the electrode was pretreated for 10 minutes using a 0.1 mol/L Na2SO4 solution at the same current density as the degradation experiment itself.
· During the AY49 degradation electrolysis process, the solution is sampled at specific times to monitor its degree of decolorization and oxidation (chemical oxygen demand-COD) and mineralization (total organic carbon content-TOC).
· The spectral absorption coefficient was used to evaluate the decolorization efficiency, based on the λmax=400 nm of the azo chromophore of the AY49 dye.
