an agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. the physical properties of the developedadsorbent were characterized using ftir. the study was realized using batch experiments. the effectsof contact time, ph, initial dye concentration, biosorbent dose and temperature were investigate...

In this paper, CuO-ZnO nanocomposite was synthesized and its photocatalytic dye degradation ability from colored wastewater was studied. Basic Red 18 (BR18) and Basic Violet 16 (BV16) were used as model dyes. The characteristics of CuO-ZnO of were investigated using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscope (SEM) and X-ray diffraction (XRD). Photocatalytic dy...

in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time,...

Background and purpose: Textile industries are among the most polluting industries regarding the volume and the complexity of treatment of its effluents discharge. This study investigated the efficiency of electrocoagulation process using aluminum electrodes in basic red 18 dye removal from aqueous solutions. Materials and Methods: This study was performed in a bipolar batch reactor with ...

dye removal from effluents of textile industries of iran was investigated through biodegradabilitymethod and membrane technology . basic, reactive,disperse and acidic dyes were selected, based onusage rate in iran. the zahen - welenze method (iso 9888) was applied to study the biodegradabilityof dyes. results showed the final cod and dye removal (%r) as (%61,% 57), (%73, %76), (%25, %14),and (%...

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...
