“…MB can cause the adverse effects such as cyanosis, vomiting, diarrhea, tachycardia, and jaundice on human beings. [3,4]. Crystal violet is another type of toxic pollutant with a poor degradability that is widely used in textile industries because of its low cost and high solubility in water [5,6].…”

Zirconium oxide/activated carbon (Zr3O/AC) composite was synthesized to remove methylene blue (MB) and crystal violet (CV) from the aqueous medium. The Zr3O/AC sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analyses (EDS), Raman spectroscopy (RS), BET surface area, and Fourier transform infrared spectroscopy (FTIR). XRD profiles confirmed the successful synthesis of the zirconium oxide/activated carbon composite. SEM images showed multideveloped walls with irregular particle size with channel arrays. The nitrogen physisorption combines I and IV types with a calculated BET surface area of 1095 m2/g. Raman spectrum illustrated a disorder of both crystalline structure and the graphitic structure. The adsorption was better fitted to the pseudo-second-order (PSO) kinetic model. Langmuir model fitted better the experimental results of MB adsorption, whereas the CV was better consistent with the Freundlich model. The obtained results suggested that the MB and CV adsorption might be influenced by the mass transfer that involves multiple diffusion steps. The maximum adsorption capacities are 208.33 and 204.12 mg/g for MB and CV, respectively. The MB and CV removal mechanisms were proposed, and statistical optimization was performed using central composite design combined with the response surface methodology.

“…Dye loaded wastewater is usually treated by various physicochemical processes. Adsorption by activated carbon is the most frequently used method for dye removal in effluents (Anbia and Salehi 2012;Ashiq et al 2012;Zhang et al 2012). However activated carbon is relatively costly to manufacture and regenerate (Al-Degs et al 2009;Cabal et al 2009;Demirbas 2009).…”

“…Many researchers have used different forms of rice waste in treating pollutants such as textile dyes and other organic chemicals. Rice husk, rice bran and rice ash were used to adsorb a number of dyes including methylene blue (Ashiq et al 2012), crystal violet (Chakraborty 2012), Brilliant Vital Red (Rehman 2011a), Direct Red-31 and Direct Orange-26 (Safa and Bhatti 2011), congo red (Wang and Chen 2009), safranin-T (Gupta et al 2006), acid yellow (Mohamed 2004), and acid blue (Mohamed 2004). But no study has focused on the use of agricultural waste as an adsorbent in combination with phytoremediation in a constructed wetland.…”

Azo dyes are commonly generated as effluent pollutants by dye using industries, causing contamination of surface and ground water. Various strategies are employed to treat such wastewater; however, a multi-faceted treatment strategy could be more effective for complete removal of azo dyes from industrial effluent than any single treatment. In the present study, rice husk material was used as a substratum in two constructed wetlands (CWs) and augmented with microorganisms in the presence of wetland plants to effectively treat dye-polluted water. To evaluate the efficiency of each process the study was divided into three levels, i.e., adsorption of dye onto the substratum, phytoremediation within the CW and then bioremediation along with the previous two processes in the augmented CW. The adsorption process was helpful in removing 50% dye in presence of rice husk while 80% in presence of rice husk biocahr. Augmentation of microorganisms in CW systems has improved dye removal efficiency to 90%. Similarly presence of microorganisms enhanced removal of total nitrogen (68% 0 and Total phosphorus (75%). A significant improvement in plant growth was also observed by measuring plant height, number of leaves and leave area. These findings suggest the use of agricultural waste as part of a CW substratum can provide enhanced removal of textile dyes.

“…Dyes are commonly used in textile, pharmaceutical, food, tanning and paper industry. [3][4][5] Removal of dyes from water sources is necessary because of their recalcitrant, toxic and non-biodegradable nature. [6][7] Presence of dye affects chemical oxygen demand (COD) of the effluent and sunlight penetration, which has a detrimental effect on aquatic life.…”

Humic acid was immobilized on a polypropylene supported sodium alginate/hydroxyethyl cellulose blend membrane in the current work. The adsorption property of this membrane for the removal of cationic dyes, namely, methylene blue (MB) and rhodamine B (RhB) was extensively studied. Batch-adsorption experiments were conducted to investigate the adsorption behavior of dyes on the membrane with variation in adsorbent mass, initial dye concentration, pH, time and temperature. The membranes were characterized by Scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDX), Fourier transform infrared spectroscopy (FTIR) and Atomic force microscopy (AFM). Prepared membranes showed more than 98% removal capacity for both dyes under optimal conditions. Kinetic experiments revealed that, the pseudo second order model exhibited best correlation with the adsorption data. Dubinin-Radushkevich model indicated that, the adsorption of dyes onto the membrane surface was by simple physisorption. The membrane was easily regenerated by simple acid treatment and its efficiency remained significant even after four adsorption cycles.
