Application of Derivative Spectrophotometry to Determine the Relation Between Color Intensity and Dye Concentration of Madder
The Derivative Spectrophotometry usually improves resolution bands, eliminates the influence of background and provides more defined fingerprints than original spectra, hence enhancing the detectability of minor spectral features. In this work, different madder types were collected and applied for dyeing woolen yarns used in Persian carpet in conventional pre-mordanting and dyeing process with ...
متن کاملDyeing Properties and Color Fabrics Using Natural Dye and Mordant
An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Fabrics dyed using myrobalan extract as natural mordants and green dye. A red color were obtained by using theses mordants. The color of dyed fabrics was investigated in CIELab L, a and b and K/S values. Finally, all dyed fabrics were tested for wash and light fastness properties as per ISO standard t...
متن کاملThe Color Removal of Dye-Containing Wastewater by Cerium (IV) Sulfate from Aqueous Solutions
In this study a giant reagent such as Ce (SO4 )2 was used for removing different initial dye concentration (10-1000 mg/l) of reactive red 31 (R.R31) less than two minutes in a laboratory scale whereas the percent of dye removal efficiency was %99.9. The Langmuir, Freundlich and Tempkin adsorption models were applied to describe the equilibrium isotherms. The Langmuir model agreed very well with...
متن کاملDecolorization of a Reactive Dye by UV-Enhanced Ozonation
In the present study the treatment efficiency of O3 and UV+O3 processes were compared for the oxidation of simulated dyebath effluent containing a mixture of a reactive dye (C.I. Reactive Blue 19) and various dye auxiliary chemicals. The color, COD and TOC removal rates were assessed for different processes. The effect of initial dye concentration and presence of sodium hydroxide and sodium car...
متن کاملbiodegradation of different concentration of dye (congo red dye) by using green and blue green algae
releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...
