“…For BR46, the sorption equilibrium was obtained after 90 min of sorption (Figure 2f). The same equilibrium time was also established in the research on Basic Red 46 sorption on pine needles [Deniz and Karaman 2011], as well as fir sawdust [Laasri et al 2007]. …”

The main purpose of the work was to check the possibility of using coconut shells for the removal of the dyes popular in the textile industry from aqueous solutions. The sorption abilities of an unconventional sorbent were tested against four anionic dyes: Reactive Black 5, Reactive Yellow 84, Acid Yellow 23, Acid Red 18 as well as two cationic dyes: Basic Violet 10 and Basic Red 46. The scope of research included investigation pertaining to the effect of pH on the effectiveness of sorption of dyes, conducted in order to determine the time of equilibrium of sorption and determine the maximum sorption capacity of coconut shells with respect to pigments. The most favorable pH of sorption for the anionic dyes and Basic Violet 10 was pH 3 and for Basic Red 46 -pH 6. The equilibrium time of sorption was the shortest in the case of acidic dyes (Acid Yellow 23/ Acid Red 18 -45 min), while the longest in the case of alkaline dyes (Basic Red 46 -90 min, Basic Violet 10 -180 min). The sorption capacity of coconut shells in relation to anionic dyes was for Reactive Black 5 -0.82 mg/g, Reactive Yellow 84 -0.96 mg/g, Acid Yellow 23 -0.53 mg/g and for Acid Red 18 -0.66 mg/g. The tested sorbent showed much higher sorption capacity with respect to the cationic dyes, i.e. Basic Violet 10 (28.54 mg/g) and Basic Red 46 (68.52 mg/g).

“…However, the desorption of surfactant from bentonite does not decrease the chemical oxygen demand (COD) (Zhu et al 1995). Waste materials, such as shells, husks, plant leaves, sewage sludge-amended soil, and wood sawdust were tested as sorbents of organic substances and heavy metals, too (Yue et al 2007;Laasri et al 2007;Mane et al 2007;Sciban et al 2007;Antoniadis et al 2007). However, most of the present sorbents often bear some disadvantages, e.g.…”

The present work provides a simple and valuable method for preparing the highly effective adsorbent. If a concentrated BPR wastewater was reused as the inclusion reactant, the sorbent will be low cost. By selecting the inclusion ligand with a special structure, we may prepare some particular functional materials to recover the valuable substances from seriously polluted wastewaters. The recommended method will play a significant role in development of advanced adsorption materials.

“…And the water including dyes exert an adverse effect on fish life [2]. Therefore, the treatment of wastewater has been a vital issue in environmental protection since some dyes and their degradation products are known carcinogens and others probable carcinogens and toxic [2,[4][5][6].…”

“…Consequently, more than 10 6 kg/year of dyes are discharged into waste streams by the textile industry [1]. The release of some dyes into water streams results in a serious environmental impact; many of the dyes cause health problems such as allergic dermatitis, cancer, skin irritation and also mutation in humans [2][3][4]. In addition, dyes absorb sunlight within water media resulting in the prevention of photosynthesis of aquatic plants.…”

The ability of polyamide 6 nanofibers membrane (P6NM) to remove acid dyes from effluent solution by adsorption has been studied. Equilibrium isotherms for the adsorption of three acid dyes, Acid blue 41 (AB41), Acid blue 78 (AB78), and Acid yellow 42 (AY42), on P6NM were measured experimentally. Simulated wastewater of acid dyes with the concentration of 10 mg/L for sorption process electrospun polyamide 6 with mass per unit area 12 g/m2 was used as the sorbent material. Ten sets of P6NM were dipped in separate simulated effluent. The weight of the original P6NM and the concentration of left solution were detected. Results were analyzed by the Langmuir equation using a linearized correlation coefficient. And it showed that all the dyes tested could follow the Langmuir adsorption isotherm, which gave excellent correlation for all the dyes.
