“…The above reasons have prompted enormous research interest in the use of agricultural waste as starting materials because of their low-cost and widespread availability. Some examples of agrowaste that have been used for the removal of dyes are palm kernel fibers [12] , coir pith [13] , sugarcane bagasse [14] , banana peel [15] , peanut hull [16] , rice bran and wheat bran [17] , rice husk [18] , tea waste [19] , waste apricot [20] , rubber seed coat [21] , coconut shell [22] , apple pomace and wheat straw [23] , halzelnut shell [24] , plum kernel [25] , corncob and barley husk [26] , bamboo [27] , grass waste [28] , pumpkin seed hull [29] and garlic peel [30] . Methyl Red (MR) is a commonly used monoazo dye in laboratory assays, textiles and other commercial products; however, it may cause eye and skin sensitization [31] and pharyngeal or digestive tract irritation if inhaled or swallowed [32] .…”

Problem statement:The aim of this study was to investigate the removal of methyl red, a mutagenic monoazo dye, from various aqueous solutions using banana pseudostem fibers of the size 212-350 micron. Approach: The parameters studied were the effect of pH, amount of adsorbent, contact time, concentration of adsorbate and agitation speed. Results: Equilibrium data were fitted to the Langmuir and Freundlich isotherm models. The data were best represented by the latter with an adsorption capacity and adsorption intensity of 0.351 and 0.302, respectively. Conclusion/Recommendations: Specific rate constants of the processes were calculated by kinetic measurements and a pseudo second order adsorption kinetics was obtained for all cases.

“…4 High concentrations of dyes in effluents cause visual pollution and may have an inhibitory effect on photosyntesis affecting aquatic ecosystems. 5 The color reduces light penetration into water, inhibits the growth of aquatic biota and interferes in gas solubility. 6,7 Furthermore, the expanded uses of azo dyes have shown that some of them and some of their reaction products such as aromatic amines are highly carcinogenic.…”

Simultaneous Determination of the Textile Dyes in Industrial Effluents by First-Order Derivative Spectrophotometry

et al. 2009

A first-order derivative spectrophotometric method for the simultaneous determination of three textile dyes, Procion Yellow HE4R, Procion Red HE7B and Remazol Black 5 (RB5), has been developed. The effects of pH, heating and ionic strength of the solution on the absorption spectra of the dyes were investigated. The wavelengths selected for the measures of the derivative signals of HE4R (395 nm , respectively. The reliability and reproducibility of the method were tested and showed recovery values of 95.7 to 109%. The proposed method was applied for the determination of dyes in binary and ternary mixtures of textile effluents and showed an estimate of the loss of dyes for the effluents between 6.67 and 28.9%.

Abstract:The azo dye and plant-derived sorbent system was investigated in this paper. Direct Orange 26 azo dye was acquired from Boruta-Zachem Kolor Sp. z o.o. Chemically modified granulated corncobs obtained from Chipsi Mais Germany were used as the biosorbent. The changes in the dye and sorbent concentrations with time were measured and used for further calculations. The experiments were carried out in a laboratory fixed bed column. Breakthrough curves were plotted for different initial concentrations, volumetric flow rates and bed heights. Sorption dynamics was described by a model presented in the literature. It was demonstrated that Infrared analysis of the system allows to determine the nature of the dye-sorbent bond. It was found that corncobs can be used as a promising sorbent material.
