natural dyeing of wool and hair with indigo Carmine c i natural blue 2 a renewable resource based blue dye
Journal of Cleaner Production, 2009Co-Authors: Sunsanee Komboonchoo, Thomas BechtoldAbstract:Abstract Indigo Carmine can be used as a source of blue dye for wool and hair dyeing. The option to use indigo Carmine in combination with other natural dyes in a one-bath procedure as a hybrid dyeing concept is of interest both for natural dyeing and for coloration of hair. The present study shows that indigo Carmine dyeing on wool exhibits the substantial sorption in the range of pH 4–5 and temperature between 40 and 60 °C. Experiments with human hair samples indicate that the experiments on wool can serve as a model that can be applied for hair dyeing. Comparisons of the energy, water and chemical consumption between two-bath dyeing with indigo and natural dyes separately and a one-bath dyeing using indigo Carmine together with other natural dyes demonstrates the advantages of the one-bath hybrid dyeing concept.

synergistic inhibition of carbon steel corrosion in 0 5 m hcl solution by indigo Carmine and some cationic organic compounds experimental and theoretical studies
RSC Advances, 2016Co-Authors: Zhe Zhang, N C Tian, Xuebing Huang, Wei Shang, Lizhu WuAbstract:The synergistic corrosion inhibition effect of indigo Carmine and three kinds of cationic organic compounds on 1045 carbon steel (CS) in 0.5 M HCl solution is reported. Electrochemical measurements showed that these three cationic organic compounds combined with indigo Carmine reduce the speed of corrosion on 1045 CS and act as effective inhibitors. The combination of indigo Carmine with BAB resulted in the best synergistic corrosion inhibition effect (S = 17.14), and the best inhibition efficiency (95.0%). SEM images and XPS data of the corroded steel surfaces suggested that the indigo disulphonate anion and organic cation could be simultaneously adsorbed on the CS surface to inhibit the corrosion of iron. The synergistic inhibition mechanism was investigated by dynamic simulations using quantum chemistry.

synergistic inhibition behavior between indigo Carmine and cetyl trimethyl ammonium bromide on carbon steel corroded in a 0 5 m hcl solution
Applied Surface Science, 2015Co-Authors: Zhe Zhang, Ningchen Tian, Xiuying Li, Lingzhi Zhang, Ling Wu, Yan HuangAbstract:Abstract This work reports on a newly observed synergistic inhibition between indigo Carmine and cetyl trimethyl ammonium bromide (CTAB) on 1045 carbon steel (CS) corroded in a 0.5 M HCl solution. The results of electrochemical measurements showed that CTAB could change indigo Carmine in a manner that would accelerate corrosion and produce an effective inhibitor. The maximal protection efficiency was significantly greater than 0.985, with the concentration of the combination inhibitors reaching approximately 5 × 10 −5 M. The microstructure of the CS corrosion surface demonstrated that the indigo disulfonate anions and cetyltrimethylammonium cations were adsorbed simultaneously on the CS surface to protect it from corrosion. Diffusion coefficient analysis and the surface concentration profiles of the corrosive species were used to investigate the synergistic effect of the indigo Carmine/CTAB combination inhibitors, and the results demonstrate the existence of synergy.

design of a silver nanoparticle for sensitive surface enhanced raman spectroscopy detection of Carmine dye
Food Chemistry, 2017Co-Authors: Yanxiong Wu, Pei Liang, Qianmin Dong, Zhi Yu, Jie Huang, Yuan Zhong, Dejiang Ni, Charles U PittmanAbstract:Abstract Flower-shaped silver nanoparticles have been successfully synthesized by a simple aqueous phase silver nitrate reduction by ascorbic acid in the presence of polyvinylpyrrolidone (PVP) surfactant. The nanoparticles diameters were adjusted from 450 to 1000 nm with surface protrusions up to 10–25 nm. The growth direction of silver nuclei is controlled by their degree of coating by PVP. The flower-shaped silver nanostructures obtained were used as stable Surface Enhanced Raman Scattering (SERS) substrates with high SERS activity for detecting Rhodamine 6 G (R6 G), at a concentration of only 10 −9 M, where the SERS signal is still clear. SERS spectra of the dye Carmine was analysed and the characteristic bands were identified. An improved principle component analysis (PCA) was used for Carmine detection, at concentrations down to 10 −8 M. The characteristic peaks of the Carmine (1019, 1360, and 1573 cm −1 ) remained at 10 −8 M. This indicated that the minimum detection limit of AgNP-based substrate for Carmine is about 10 −8 M.

Sentinel lymph node biopsy using indigo Carmine blue dye and the validity of '10% rule' and '4 nodes rule'
Breast, 2012Co-Authors: Takashi Nagao, Takashi Hojo, Hiroaki Kurihara, Takayuki Kinoshita, HIROMICHI TSUDAAbstract:This is the study which assessed sentinel lymph node biopsy (SNB) using indigo Carmine blue dye and the validity of the '10% rule' and '4 nodes rule'. Patients (302) were performed SNB using the combined radioisotope (RI)/indigo Carmine dye method. Excised SLNs were confirmed whether they were stained and numbered in order of RI count and the percentage of radioactivity as compared to the hottest node was calculated. The relationship between histological diagnosis, dyeing and RI count was assessed. All the patients were detected SLN. Positive nodes were identified in 84 (27.8%) patients and were identified up to the third degree of hottest. All the hottest positive nodes were stained by indigo Carmine. From the results, removing the three most radioactive SLNs identified all cases of nodal metastasis without complications. These stopping rules were valid and useful under indigo Carmine use too. ?? 2011 Elsevier Ltd.
