“…Whereas in the case of Chemically activated baggase rate of dye uptake increases rapidly from 78.09% to 86.35% with rising temperature at 30°C to 50°C with 4 gm/l dose in 30 minutes from 100 ppm dye solution, since the adsorption rate increase as the diffusion coefficient rises with temperature. [5]. For adsorption of dye using baggase (raw and chemically activated) adsorbent there is the possibility of intra-particle diffusion.…”

“…Basic dyes are the brightest class of dyes [5] and are applied widely in small scale industries like textile, carpets and wool industries whose discharge bearing dyes throught effluents are added into natural streams [6]. In dying industry above 30-60 litres of water is consumed per kg of cloth dyed and large quantities of effluents are released during process [7].…”

A Ab bs st tr ra ac ct t. The adsorption potential of agricultural (sugarcane) by-product, the baggase was investigated in batch experiments with two different forms i.e., raw and chemically activated forms, for the removal of Methylene Blue dye, with different parameters like dye concentration, contact time, temperature and adsorbent dose. The removal is better and more effective with chemically activated baggase in comparison to the raw baggase. An average percent removal difference between the two adsorbents of around 18% was achieved under the different conditions in the experiment. The data fit well in the Freundlich isotherm.

The aim of the research is to determine the efficacy of using Poly vinyl alcohol (PVA) coated carbon black to treat wastewater having low dye concentration. The effect of pH, conc. and dose on the adsorption isotherm were studied. Studies conducted to assess the ability of PVA coated carbon black to adsorb dye from wastewater was found to be as an much effective adsorbent. Batch kinetic and isotherm experiment were conducted.

“…Relative to the dye toxicity, a rodent must be administered 100 mg into the eye over a 24 h period for a moderate reaction and the oral LD 50 for rodents was reported as 8980 mg dye/kg for PB dye (Epolito, 2005). The estimated LC 50 for fish over 14 days was estimated as 1500 mg L −1 for PB dye Due to its high toxicity, it is necessary to remove this dye from aqueous effluents.…”

“…Granular activated carbon is the most preferable adsorbent and has been used successfully in adsorption processes (McKay, 1982), but is expensive in comparison with other sorbents. Consequently, many investigators have studied alternatively the possibility of using low cost substances, such as: chitin , chitosan (Wong et al, 2008), perlite (Doğan and Alkan, 2003), natural clay (El-Geundi, 1991; El-Geundi 1993), bagasse pith (McKay et al, 1987;McKay et al, 1988;Nassar et al, 1996), coal fly ash Mall et al (1996), and Bailey et al (1999) have presented a critical review of low cost adsorbents for waste and wastewater treatment.…”

Abstract. In this study, the application of chitosan for the removal of Procion MX-R dye from synthetic reactive dye wastewater (SRDW) was investigated under ambient conditions. The optimum conditions for the adsorption of Procion MX-R dye onto the adsorbent was found to be: pH (4.0), adsorbent dose (1.0 g), temperature of 35°C for an initial Procion MX-R dye concentration of 100 mg/L. Langmuir and Freundlich adsorption isotherm models were applied which fitted the data with R 2 value of 0.990. The adsorption of Procion MX-R on chitosan was confirmed by SEM study, as it showed the change in characterization before and after adsorption. The kinetic results showed that the rate of dye adsorption follows pseudo-second-order model for the dye concentration range studied in the present case. In addition, various thermodynamic parameters, such as standard Gibbs free energy (ΔG°), standard enthalpy (ΔH°) and standard entropy (ΔS°) have been calculated. It has been found that the chitosan/dye interaction was feasible, spontaneous and exothermic in nature. As a result, chitosan have been shown to be a very efficient and low-cost adsorbent, and a promising alternative for eliminating dyes from industrial wastewaters.
