“…With the rapid growth in industries, the consumption of dyes has also increased exponentially in textiles, leather, printing paper, pharmaceutical, cosmetics, and in many other sectors 1,2 . Wastewater released from these industries contains variety of untreated dyes which are harmful to human life as well as for aquatic organisms.…”

Waste cigarette filters (CFs) were recycled and modified with a nontoxic and low‐cost citric acid (CA). The modified CFs were employed in the adsorptive removal of methylene blue (MB) dye from aqueous medium. The influence of pH, contact time, initial dye concentration, and adsorbent dose on adsorption of MB dye was evaluated. The adsorption studies were conducted by employing linear and nonlinear Langmuir and Freundlich isotherm models. The adsorption capacity of CF obtained through linear and nonlinear Langmuir model were 88.02 and 94 mg g−1, which improved up to 163.93 and 168.81 mg g−1, respectively, after the introduction of functional groups in CF‐CA. The adsorption kinetics data were well fitted by pseudo‐second order kinetics with coefficient of regression (R2) closed to unity. The removal efficiency of CF‐CA was 97% at equilibrium time of 4 h. Desorption studies indicated that CF‐CA could be regenerated by using HCl (0.1 M) and desorption efficiency was up to 82% upon second cycle of reusability experiment. This study proposed a green and economical use of recycled CFs in dyes wastewater treatment, simultaneously reducing the negative environmental impact due to their improper disposal.

“…Due to this problem, different treatments have been used for the remediation of environments contaminated by dyes, among them oxidation or ozonation, electrochemical treatment, reverse osmosis, precipitation, coagulation and flocculation, membrane separation and photochemical degradation can be mentioned [9,10]. However, these methods are not widely used due to their high cost [10].…”

Effluents from textile processes, when discarded of inappropriately, have been shown to be a major environmental concern. In this way, different methods can be used, among them adsorption is an economical and efficient technique in the removal of dyes. Therefore, we propose to analyze the adsorptive capacity of bacterial cellulose (CB) against effluents containing the dye Remazol Black B (RBB). CB was produced by the bacterium Gluconacetobacter hansenii and characterized by the techniques of FTIR, DRX, TGA / DTG and pH (PCZ). The RBB removal tests were initially performed at different pHs. From the best experimental condition, new tests were performed at temperatures of 30, 40, 60 and 100 ± 2 °C, 150 rpm, pH 3.5, using 0.5 g of adsorbent in the concentrations of dye from 25 to 65 mg•L -1 . The kinetic study showed that the system balance was achieved in 80 minutes. The experimental data were better described by the pseudosecond order model. The equilibrium results showed that the experimental data fit the Langmuir model (qmax 17.513 mg•g -1 ). The thermodynamic parameters of adsorption showed that the process is exothermic, not spontaneous and also presented low system randomness. The activation energy (Ea) was 23.8 kJ•mol -1 characterizing physical adsorption. The residual water was not toxic to animal or microbial cells. Bacterial cellulose proved to be a good low-cost adsorbent, easy to acquire and which can be used in the adsorption process.
