“…There are over 100,000 types of dyes available commercially, with annual production exceeding one million tons (Christie 2007). It is estimated that about 20% of dyes are lost throughout the dyeing process and are discharged directly into the environment (Houas et al 2001;Hussein 2013).…”

“…Synthetic dyes are preferred because of color availability, easy to use, persistent, quick-setting compared with natural dyes (Chowdhury and Saha 2010;Kurniawan, Sutiono et al, 2012). Large volumes of colored effluents including hazardous substances for human health and natural ecosystems generate from several industries that need to be effectively treated (Christie, 2007;Petrucci, Di Palma et al, 2015). The release of these wastewaters in the environment is a significant source of visual pollution, eutrophication and serious environmental impacts because of highly toxic components.…”

ultrasound assisted modification of boron enrichment process waste and using for methylene blue removal from aqueous solutions, Global NEST Journal, 20(X), XX-XX. AbstractIn this study, raw boron enrichment waste was treated with hydrochloric acid and ultrasound at 35-kHz frequency for 60 minutes. To optimize the adsorption conditions for removal of methylene blue (MB) from synthetic wastewaters using raw boron enrichment waste (BEW), acid modified boron enrichment waste (HBEW) and ultrasound modified BEW (UBEW) by adsorption process and to compare the adsorption efficiency of chemical and ultrasonic modifications of BEW were aimed. The optimum adsorption conditions were determined economically and eco-friendly aspect and MB removal percents were found as 80%, 80% and 92% at optimum conditions for BEW, HBEW and UBEW, respectively. The maximum regression coefficient values were obtained as 0.911, 0.998 and 0.984 for BEW, HBEW and UBEW, respectively at Langmuir isotherm model. The adsorption rate was fitted well to pseudo-second order kinetics according to a good correlation coefficient. The adsorption of MB onto adsorbents studied is spontaneous in nature and feasible because of negative ∆G values. The results indicated that the boron enrichment process waste could be a suitable adsorbent for removal of MB from aqueous solution. The maximum adsorption capacities were equal to about 107,0 mg/g, 160,7 mg/g and 145,3 mg/g for BEW, HBEW and UBEW adsorbents at 298 K, respectively. The maximum dye removal percent was achieved for UBEW as 92% and ultrasound assisted modification was found more efficient method compared with acidic modification for MB removal.

“…The water bodies are continuously polluted due to the unscientific methods adopted by the chemical, textile, paper, and pulp industries, and so forth, during the discharge of toxic and hazardous chemicals [1][2][3][4][5]. Complexity of the dye molecules does not favour the natural process of degradation and also during certain instances incomplete degradation or transformation may generate carcinogenic byproducts [6][7][8][9].…”

Calcium oxide was used as photocatalyst for the degradation of indigo carmine dye solution in the visible, long UV, and short UV radiation. We have investigated the effectiveness of degradation of indigo carmine dye solution at pH 9 and 12 using calcium oxide with the particle size of 30-36 nm by varying the concentration, dose of adsorbent, and duration. It has been found that the degradation of indigo carmine dye is effective at pH = 9, when 0.12 g of calcium oxide was used. The nature of interaction between calcium oxide and indigo carmine dye was discussed.
