ginger waste material (gwm) has been utilized as adsorbent for removal of hazardouspatent blue vf (pbvf) dye from aqueous solution. batch adsorption experiments wereperformed as a function of ph, contact time, dye concentration, adsorbent dose and temperature.the optimum ph required for the maximum adsorption was found to be 2. the experimentalequilibrium adsorption data were tested using langm...

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...

Environmental release of benzidine-based dyes is a matter of health concern. Here, a microbial consortium was enriched from textile dye contaminated soils and investigated for biodegradation of the carcinogenic benzidine-based dye Trypan Blue using wheat bran (WB) as growth medium. The PCR-DGGE analysis of enriched microbial consortium revealed the presence of 15 different bacteria. Decolorizat...

Intelligent manufacturing for the fabric dyeing industry requires high-performance recipe recommendation systems. Nowadays, recommending recipes by mining data has become a new direction development of As one indispensable parts in system development, pre-processing needs more than routine steps such as removal missing and outliers. Considering that dyes can have very different coloration prope...

A basic dye is usually obtained in the form of the salt some of which may be transformed in aqueous solution to free base (the m o u n t depending on the "apparent" dissociation constant of the dye and the pH value), and in the range of pH values generally employed with living cells (approximately between pH 5 and 9.5) both forms of dye must be considered. In this range methylene blue, for exam...

BACKGROUND In this research, response surface methodology (RSM) was applied to optimize Reactive Blue 19 removal by activated carbon from pomegranate residual. A 24 full factorial central composite design (CCD) was applied to evaluate the effects of initial pH, adsorbent dose, initial dye concentration, and contact time on the dye removal efficiency. METHODOLOGY The activated carbon prepared ...

poly urea-formaldehyde was synthesized simply and rapidly from urea and formaldehyde by condensation polymerization and studied for the sorption of trace acid blue from aqueous solution. the optimum ph value for sorption of the acid blue was 4. experimental results showed that the sorption capacity of poly urea-formaldehyde for acid blue was determined. the synthetic polymer can be reused for 5...
