“…Therefore, the ion exchange process is the main mechanism that governs adsorption process, but surface interactions mediated by van der Waals and π-π interactions, which occur between aromatic structure of AB 113 and IRA 402(Cl − ), must also be taken into account. Similar results have been presented in the literature [15,16,21,22].…”

“…Second, the swollen resin was transferred in a 1000 mL Berzelius flask and stirred for 2 h at 100 rpm with horizontal stirrer mixer at laboratory temperature with 500 mL 1 M HCl. The resin activated in Cl − form was washed with ultrapure water until the pH of supernatant was neutral and dried for a few days in a desiccator up to the constant mass of IRA 402(Cl − ) detection [15,16,20].…”

“…Given their major toxicity, an ideal method should be able to remove dyes in high concentrations from wastewater in a very short time without producing secondary pollution. Among the multitude of conventional methods, the ion exchange process offers one of the best removal efficiencies for azo dyes [15,16]. The first synthetic ion exchange resins of phenolformaldehyde type, modified with sulfonic groups were obtained as early as 1935 by Adams and Holmes.…”

Despite Acid Blue 113 (AB 113)’s extensive use and negative environmental impact, very few studies have focused on its efficient and environmentally friendly removal. This research aims the removal of AB 113 from environmental aqueous media and its consequent enzymatic biodegradation. A strongly basic anion exchange resin in Cl− form, Amberlite IRA 402 (IRA 402(Cl−)) was used for AB 113 adsorption and a laccase was used to further biodegrade it. For the first time, two novel, efficient and environmentally friendly physical–chemical and biological assays for AB 113 wastewater removal and subsequent biodegradation were combined. The adsorption of AB 113 onto IRA 402(Cl−) was tested in batch and continuous flux modes. Influence of contact time, concentration and desorption in acidic media were evaluated. The kinetic data were best modulated by the Lagergren model with R2 = 0.9275. The Langmuir isotherm model best fitted the experimental data, and the maximum adsorption capacity was 130 mg/g. Dye, resin and AB113 loaded resin were characterized by thermogravimetry and FTIR to evaluate their physical chemical properties modification. Based on the performed studies, a consecutive methodology is proposed, incorporating the ion exchange process in the first stage and the biodegradation process in the second. Thus, in the second stage the residual concentration of AB 113 is reduced by an efficient bio-degradation process produced by the laccase at pH = 4.

“…The experimental data obtained under the influence of the contact time were processed based on first order kinetic model, pseudo-second-kinetic model and the Morris Webber kinetic model [18][19][20][21] (8) where: qe, qt are the quantity of Cu(II) and Fe(III) retained at equilibrium and at time t, respectively, k1 and k2(min -1 ) are the rate constants of the sorption process of first order and second order model, respectively. The C is a dimensionless constant, which represents the amount of metal retained on the surface of the biomaterial and kid(min -1 ) is the value of the intra-particle diffusion constant.…”

This study is based to a new concept, to use maize stalk for specific sorption and recovery of Cu(II) and Fe(III) from synthetic solutions. Thus, the sorption properties of the biomass resulting from the recycling of the maize stalk that reached maturity (autumn) were studied. In the first stage, the sorption properties of the maize stalk were evaluated in batch system. Moreover, in terms of water quality improvement several key parameters that influence the sorption equilibrium were evaluated. The effect of contact time (0-120min) and cations initial concentration (investigated range: 0.05-0.4 mg/L) on biomaterial sorption capacity were assessed. Kinetic studies were performed taking into consideration the initial concentration of metallic cation. The experimental data were analyzed based on first order kinetic model, pseudo-second-kinetic model and Morris Webber kinetic model. The kinetics of sorption was in accordance with the pseudo - second - kinetic model as the correlation coefficients showed (R2=0.9940 for Cu(II) and R2=0.9999 for Fe(III)). Moreover the desorption study was evaluated with hydrochloric acid and have detected to be 63% and 89% for Cu(II) and Fe(III) when 4M HCl is used. The surface of the maize stalk loaded with Cu(II) and Fe(III) was characterized by various specific techniques such as FTIR-ATR, SEM, and TG. Experimental results revealed that cations sorption process takes place on the sorbent surface. The sorption rate of each metallic cation is controlled by the formation of chemical bonds with surface polar groups. Their presence on biomass structure, evidenced by FTIR-ATR analysis, explains the behavior of maize stalk as a weak ion exchanger acid.

“…Bioreactors have played an important role in the detoxification of hazardous pollutants and have been successfully applied in ex-situ bioremediation strategies [6]. Bioreactors are basically tanks in which living organisms carry out biological reactions [7][8][9]. These types systems display as main advantage a larger control of environmental and physico-chemical conditions affecting rates and extents of microbial growth and oil transformation such as oxygen supply, optimal pH, temperature and specific quantity nutrient providing an increase on biodegradation [7].…”

The purpose of this study was to identify the optimal conditions for the operation of biological treatment plant by carrying out biodegradability tests for geothermal wastewaters with high salt content. The biodegradation tests for geothermal wastewaters were carried out in a discontinuous flow bioreactor. The phases of the biodegradation process were: adaptation of the biological sludge, control of the biological treatment process, experiments in the laboratory bioreactors (BATCH). The results of the biodegradability tests revealed that geothermal waters with high salt content influence the treatment process. The dilution of these waters with domestic water up to chlorine concentrations below 800 mg L-1, makes the purification process to have a good biodegradation yields for CCO-Cr (about 75%) and CBO-5 (about 72%). If these geothermal wastewaters are not diluted to concentrations lower than 800 mg L-1, the biological sludge after 6 days is mineralized, which makes the use of biological treatment plant to be impossible.
