The actual quantity of dyes currently consumed around the world is unknown but it is estimated that up to 700,000 tonnes/year of dyes (including cationic dyes) were consumed in the 1980s (Zollinger, 1987). 2% of dyes produced are discharged directly in aqueous effluent, and 10% are subsequently lost during the coloration process (Easton, 1995).
NETZSCHFeinmahltechnik is one of the market leader in wet grinding technology. The bundling of processrelated knowhow and the extensive machine program from laboratory to production machines to complete production lines is our strength. Agitator bead mills are grinding machines for ultrafine processing of solids in liquids.
Simultaneous Removal of Dye and Chemical Oxygen Demand from Aqueous Solution by Combination Treatment with Ozone and Carbonaceous Material Produced from Waste Biomass
textile dyes are lost during the dyeing process, and 220% is discharged as effluent in the environment. There are several different kinds of dyes, such as reactive azo dye, metal complex, and cationic and anionic dyes [4]. Basic Violet 16 (BV 16) is a cationic dye, highly water soluble and nonvolatile which is

Yan Lin, a,b, * Guigan Fang, a,b,* Yongjun Deng, a,b Kuizhong Shen, a,b Ting Wu, a,b and Man Li a,b Eucalyptus bleached chemical pulp was fibrillated using a PFI pulp beater and ball mill method and was modified by acryloyl chloride.
cost dye adsorbent from aqueous solutions. Viscose waste as cellulosic fibers are supposed to give an answer to finding lowcost adsorbent materials. In this research work, viscose fiber wastes (VF) were modified by selective oxidation to improve the ability of absorbing cationic dyes .
dye process. Due to treatment for these colourful wastewaters it can be applied many different methods such as adsorption, chemical oxidation, coagulation, membrane filtration. In this study, decolorization of cationic dye (Basic Blue 41) from local textile mill w as
Adsorption of malachite green and crystal violet cationic dyes from aqueous solution using pumice stone as a lowcost adsorbent: kinetic, equilibrium, and thermodynamic studies
Negative values of ΔG 0 showed the spontaneity of the MG adsorption process. However, positive values of ΔG 0 showed that the EBT uptake by almond shell is not a spontaneous reaction. The results indicate that almond shell is a promising alternative for the biosorption of anionic (EBT) and cationic (MG) dyes from aqueous solutions.
cationic dyes from cationic dyeable polyester isvery difficult because the dyes are held with fibre by a strong electrostatic force. The most widely used stripping agents for direct, acid" azo, disperse, azoic and reactive dyes are the reducing agents such as sodium hydrosulphite and .
May 03, 2012· Basic dyes dyeing are carried out in acidic form. Dyeing process for different fibers are varies. Properties of basic dyes: Like other dyes; basic dyes have some own characteristics. Followings are the main characteristics of basic dyes: Basic dye is a synthetic class dye. Cationic part of the salt is responsible for color production.
Mar 10, 2013· Benefit of Cationic Starch in Paper mill Industry: Cationic starch enhances paper strength, water drainage, retention, improve paper quality; reduced dusting, linting and size addition; greater control of paper making process hence less paper web breaks and improve paper machine runnability as well as productivity.
Ball milling process Magnetite nanoparticles Heterogeneous sonoFenton Textile dye Wastewater treatment ABSTRACT The removal of basic violet 10 (BV10), which is known as a cationic dye, from aqueous solution was studied by employing a heterogeneous sonoFenton process over the nanosized magnetite (Fe 3O 4) which had been pre

Dyes are classified according to their solubility and chemical properties. Acid dyes are watersoluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber.
