Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs of natural dye extraction engendered the discovery of synthetic dyes from petrochemical compounds. Nowadays, they are dominating the textile market, with nearly 8 × 105 tons produced per year due to their wide range of color pigments and consistent coloration. Textile industries consume huge amounts of water in the dyeing processes, making it hard to treat the enormous quantities of this hazardous wastewater. Thus, they have harmful impacts when discharged in non-treated or partially treated forms in the environment (air, soil, plants and water), causing several human diseases. In the present work we focused on synthetic dyes. We started by studying their classification which depended on the nature of the manufactured fiber (cellulose, protein and synthetic fiber dyes). Then, we mentioned the characteristics of synthetic dyes, however, we focused more on their negative impacts on the ecosystem (soil, plants, water and air) and on humans. Lastly, we discussed the applied physical, chemical and biological strategies solely or in combination for textile dye wastewater treatments. Additionally, we described the newly established nanotechnology which achieves complete discharge decontamination.

Porous Graphitic carbon nitride(pg-C 3 N 4 ) possessing hierarchical pores and lamellar nanostrucutres was synthesized in the absent of templates by pyrolysis of the solution-assisted mixing dual-precursors. The samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N 2 porosimeter, X-ray photoelectron spectroscopy, UV-Vis andphotoluminescence spectroscopy.The photocatalytic activities of as-prepared materials for degradation of methyl violet were studied. The results show that the as-prepared g-C 3 N 4 consists of well-dispersed layers with uniform sizeand hierarchical (Meso/Macro) pores in the nanosheets, which favor photogenerated electron-hole pairs'separation, and the degradation of methyl violet conforms to the quasi-first-order kinetic model. The porous g-C 3 N 4 synthesized by optimizing precursors' ratios exhibited faster degradation rate than g-CN material in the process of photocatalyzing methyl violet andthe degradation rate was over 93 % after irradiation of 180 min, implying that the as-prepared hierarchically porous g-C 3 N 4 is a high-effective and metal-free photocatalytic material for degradation of pollutants.

“…Generally, it is very small for physical adsorption, while it is larger for chemical adsorption. The adsorption rate constant obtained by fitting the pseudo-second-order kinetic model at different temperature can be introduced into the linearized Arrhenius equation [21]: (6) where k 2 is the pseudo-second-order kinetic rate constant, A is Arrhenius factor, E a is the activation energy of adsorption (J/mol), R is the universal gas constant (8.314 J/mol/K) , T shows the absolute temperature (K).…”

“…While these approaches are mainly applied to treat concentrated copper-containing wastewater, adsorption is a common and easy method to treat dilute wastewater [5]. Recently, many studies have shown that microorganism biomass can be used as adsorbent to remove micro-pollutants from wastewater [6,7,8]. The microorganism biomass are economic materials because they are easy to grow using inexpensive and abundant carbon sources.…”

Adsorption of copper ions on Magnolia officinalis residues after solid-phase fermentation with Phanerochaete chrysosporium

et al. 2019

The disposal of residues while manufacturing Chinese medicine has always been an issue that concerns pharmaceutical factories. Phanerochaete chrysosporium was inoculated into the residues of Magnolia officinalis for solid-phase fermentation to enzymatically hydrolyze the lignin in the residues and thus to improve the efficiency of removal of the copper ions from residues for the utilization of residues from Chinese medicine. With the increase in activities of lignin-degrading enzymes, especially during the fermentation days 6 to 9, the removal rate of copper ions using M. officinalis residues increased dramatically. The rate of removal reached the maximum on the 14th day and was 3.15 times higher than the initial value. The rate of adsorption of copper ions on the fermentation-modified M. officinalis residues followed the pseudo-second-order kinetics. The adsorption isotherms were consistent with the Freundlich models. The adsorption enthalpy was positive, indicating that it was endothermic and elevation in temperature was favorable to this adsorption process. The adsorption free energy was negative, implying the spontaneity of the process. The copper ions adsorbed could be effectively recovered using 0.2 M hydrochloric acid solution. After five successive cycles of adsorption-regeneration, the fermentation-modified M. officinalis residues exhibited a stable adsorption capacity and greater reusability. The M. officinalis residues fermented with P. chrysosporium are low-cost and environmentally friendly copper ions adsorbent, and this preparation technique realizes the optimum utilization of Chinese medicine residues.
