Textile dye dermatitis
J Am Acad Dermatol 1995 Apr;32(4):631-9.PMID:7896955DOI:10.1016/0190-9622(95)90350-x.
The literature concerning textile dye dermatitis published during the last decade was reviewed. Sixty-one cases of dye-allergic contact dermatitis in which the presentation or course of the dermatitis was unusual or the dye allergen was one not previously reported have been described. The four new dye allergens discovered were Disperse Blue 106, Disperse Blue 85, Disperse Brown 1, and Basic Red 46. The incidence of dye dermatitis varied from 1% to 15.9% depending on the country, patient sample, and number of dyes in the patch test series. The 10 new dye allergens discovered in these studies were Disperse Blue 153, Disperse Orange 13, Basic Black 1, Basic Brown 1, the acid dyes Supramine Yellow and Supramine Red, the direct dye Diazol Orange, the basic dye Brilliant Green, Turquoise Reactive, and Neutrichrome Red. Disperse Blue 106 and Disperse Blue 124 were shown to be the strongest clothing dye sensitizers to date. Standard screening patch test series were found to be inadequate for the detection of textile dye sensitivity; therefore textile dye patch test series should be used. It is difficult to determine whether the incidence of dye dermatitis is increasing or decreasing because controlled epidemiologic studies are lacking, but data suggest that textile dye sensitivity is more common than previously believed.
Effects of temperature and pH on adsorption of Basic Brown 1 by the bacterial biopolymer poly(gamma-glutamic acid)
Bioresour Technol 2008 Mar;99(5):1026-35.PMID:17462883DOI:10.1016/j.biortech.2007.03.008.
Poly(gamma-glutamic acid) (gamma-PGA), an extracellular polymeric substance (EPS) synthesized by Bacillus species, was explored to study its interaction with the Basic Brown 1 dye by conducting a systematic batch adsorption study as affected by two critical parameters, temperature and pH. Adsorption isotherms were closely predicted by Temkin equation among the eight isotherm models tested. The rate of adsorption was very rapid attaining equilibrium within 60 min and the kinetics were well described by both modified second-order and pseudo second-order models. Boyd's ion exchange model, which assumes exchanges of ions to be a chemical phenomenon, also fitted the kinetic data precisely. The adsorption rate increased with increasing solution temperature, however, a reversed trend was observed for the adsorption capacity. Changes in enthalpy, entropy and free energy values revealed dye adsorption by gamma-PGA to be an exothermic and spontaneous process involving no structural modification in gamma-PGA, whereas the activation energy of 37.21 kJ/mol indicated dye adsorption to be reaction-controlled. Following a rise in solution pH, the dye adsorption increased and reached a plateau at pH 5, while the maximum release of dye from spent gamma-PGA occurred at pH 1.5, suggesting a possible ion exchange mechanism. Ion exchange adsorption of basic dyes by gamma-PGA was further proved by the presence of two new IR bands at approximately 1600 and 1405.72 cm(-1), representing asymmetric and symmetric stretching vibration of carboxylate anion, for dye-treated gamma-PGA.
Preparation of highly porous carbon from fir wood by KOH etching and CO2 gasification for adsorption of dyes and phenols from water
J Colloid Interface Sci 2006 Feb 1;294(1):21-30.PMID:16111690DOI:10.1016/j.jcis.2005.06.084.
Fir wood was first carbonized for 1.5 h at 450 degrees C, then soaked in a KOH solution KOH/char ratio of 1, and last activated for 1 h at 780 degrees C. During the last hour CO2 was poured in for further activation for 0, 15, 30, and 60 min, respectively. Carbonaceous adsorbents with controllable surface area and pore structure were chemically activated from carbonized fir wood (i.e., char) by KOH etching and CO2 gasification. The pore properties, including the BET surface area, pore volume, pore size distribution, and pore diameter, of these activated carbons were first characterized by the t-plot method based on N2 adsorption isotherms. Fir-wood carbon activated with CO2 gasification from 0 to 60 min exhibited a BET surface area ranging from 1371 to 2821 m2 g(-1), with a pore volume significantly increased from 0.81 to 1.73 m2 g(-1). Scanning electron microscopic (SEM) results showed that the surfaces of honeycombed holes in these carbons were significantly different from those of carbons without CO2 gasification. The adsorption of methylene blue, Basic Brown 1, acid blue 74, p-nitrophenol, p-chlorophenol, p-cresol, and phenol from water on all the carbons studied was examined to check their chemical characteristics. Adsorption kinetics was in agreement with the Elovich equation, and all equilibrium isotherms were in agreement with the Langmuir equation. These results were used to compare the Elovich parameter (1/b) and the adsorption quantity of the unit area (q(mon)/Sp) of activated carbons with different CO2 gasification durations. This work facilitated the preparation of activated carbon by effectively controlling pore structures and the adsorption performance of the activated carbon on adsorbates of different molecular forms.
Isotherm parameters for basic dyes onto activated carbon: comparison of linear and non-linear method
J Hazard Mater 2006 Feb 28;129(1-3):147-50.PMID:16298056DOI:10.1016/j.jhazmat.2005.08.022.
Equilibrium sorption experiments were carried out at 305 K with four different basic dyes basic red 9 (BR9), basic violet 3 (BV3), Basic Brown 1 (BB1) and basic violet 10 (BV10) onto activated carbon. The isotherm parameters were estimated linear and non-linear regression analysis. Non-linear method was found to be more appropriate method for estimating the isotherm parameters. The sorption capacity of activated carbon to uptake cationic dye ions in the increasing order was given by: BR9 (131 mg/g)< BV3 (247 mg/)< BV10 (259 mg/)< BB1 (404 mg/g).
Synthesis of Fe-doped Bi2O3 nanocatalyst and its sonophotocatalytic activity on synthetic dye and real textile wastewater
Environ Sci Pollut Res Int 2016 Oct;23(20):20100-20110.PMID:26786580DOI:10.1007/s11356-015-5951-z.
The catalysts such as Fe, Bi2O3, and Fe-doped Bi2O3 were synthesized for the sonophotocatalytic treatment of synthetic dye and real textile wastewater. The resultant catalysts were characterized for its size and uniform shape using x-ray diffractogram (XRD) and scanning electron microscopy (SEM) which signified the nanorod shape formed Bi2O3. The higher ultraviolet light absorbance capacity of the catalysts was also evident using diffuse reflectance spectroscopy (DRS). Initially, the effect of conventional parameters such as initial pH, gas bubbling (argon, oxygen, air and nitrogen) and oxidant addition (H2O2 and peroxymonosulfate) in the presence of sonolysis (22 and 37 kHz frequency) and photolysis (UV-C light) on 10 ppm Basic Brown 1 dye was studied. The results showed that highest decolorization of 62 % was attained for 3 g/L peroxymonosulfate under 37 kHz frequency sonolysis treatment. Secondly, with the catalyst study, highest of 46 % dye color removal was obtained with 4 g/L Fe under 37 kHz frequency sonolysis treatment. The sonophotocatalytic treatment of dye with Fe-doped Bi2O3 catalyst in combination with peroxymonosulfate showed highest color removal of 99 %. Finally, the sonophotocatalytic treatment of real textile wastewater in the presence of 3 g/L Fe-doped Bi2O3 and 6 g/L peroxymonosulfate reduced the total organic carbon (TOC) and chemical oxygen demand (COD) level to 77 and 91 %, respectively, in 180 min. The reported treatment process was found to treat the synthetic dye and real textile wastewater effectively.
