Adsorption and Removal of Acid Blue 40 on Polyaniline Materials

Muhammad, et al. Materials, 2019, 12(18), 2854.

Acid blue 40 (AB40) is one of the dyes commonly found in industrial wastewater. Polyaniline (PANI), magnetic oxides and their composites (PANI/Fe3O4) were used as adsorbents to remove AB40 dye from water.
Adsorption behavior of acid blue 40 by different adsorbents
· The maximum adsorption capacities of Fe3O4, PANI and composite materials are 130.5, 264.9 and 216.9 mg/g respectively. That is, the interaction of AB40 dye with PANI is higher than that of Fe3O4 and composite materials.
· The enhanced adsorption on PANI can be attributed to the electrostatic interactions between PANI and the oppositely charged sites of AB40. More active sites that generate physical forces also enhance the adsorption of dyes on polyaniline.
· The enhanced adsorption on PANI also benefits from its smaller activation energy value than Fe3O4 and PANI/Fe3O4 composites.

Thermal-Induced Nonlinear Optical Response of Acid Blue 40

Pramodini S, et al. Current Applied Physics, 2013, 13(7), 1175-1182.

Acid blue 40 is an anthraquinone dye with interesting optical properties. The thermally induced third-order nonlinear optical properties of acid blue 40 in N,N-dimethylformamide solution (DMF) can be studied by z-scanning technique under a continuous wave HeeNe laser at a wavelength of 633 nm.
· Acid blue 40 exhibits nonlinear absorption and nonlinear refraction under experimental conditions.
· For lower concentrations, acid blue 40 shows both saturation absorption (SA) and reverse saturation absorption (RSA), and as concentration increases, RSA dominates.
· The self-diffraction ring pattern due to refractive index changes was observed to increase with increasing concentration, which was attributed to thermally induced nonlinearity.
· The acid blue 40 dye exhibits strong optical power limitation based on the RSA process under continuous wave laser at the experimental wavelength.

Photo-Assisted Electrochemical Degradation Method for Acid Blue 40

Moraes P B, et al. Journal of Environmental Science and Health, Part A, 2007, 42(14), 2131-2138.

Light-assisted electrochemical technology has been used for color, total organic carbon (TOC), and chemical oxygen demand (COD) degradation of textile wastewater. The electrochemical degradation process in a 18L medium test tube flow reactor of 70%TiO2/30%RuO2 DSA can achieve effective decolorization of synthetic acid blue 40 solutions and real dye factory wastewater.
Decolorizing effect for acid blue 40
· Acid blue 40 has a colorless leuco-form as an impurity. Both compounds form a reversible redox couple and obey a simple electron transfer mechanism.
· The electrochemical process has shown efficiency on dye house effluent, been capable to remove 78% of color.
· The photo-electrochemical process has shown able to remove 85% of color using 80 mA cm-2 in 90 min of processing and with energy consumption of 1.388 KWh m-3.
· Furthermore, 70% of initial color was degraded within the first 15 min of the photo-electrochemical process.
