“…Dyes are widely used in various industries such as textiles, leather, and paper, and it has been reported that about 30% of synthetic dyes are discharged into the environment [ 8 , 9 , 10 ]. Dye wastewater is complex and difficult to degrade, contains chromogenic and polar groups, and can cause eutrophication of water bodies [ 11 , 12 , 13 ]. Dyes can induce allergies and cancer, damage the respiratory system, nervous system and skin, and cause harm to the human body.…”

Graphitic phase carbon nitride (g-C3N4) is a promising photocatalytic environmental material. For this study, the graphitic phase carbon nitride was prepared using a thermal polymerization method. The characteristic peaks, structures, and morphologies were determined using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), and scanning electron microscopy (SEM), respectively. Under the synergetic visible light catalysis of H2O2 and Na2S2O8, the degradation effects of g-C3N4 on the anionic dye methyl orange (MO) and the cationic dye rhodamine b (Rhb) were investigated. The effects of adding different volumes of H2O2 and Na2S2O8 were likewise tested. The results showed that the above two synergistic systems increased the degradation rates of MO and Rhb by 2.5 and 3.5 times, respectively, compared with pure g-C3N4, and that the degradation rates of both MO and Rhb reached 100% within 120 min and 90 min, respectively, in accordance with the primary reaction kinetics. When H2O2 and Na2S2O8 were added dropwise at 10 mL each, the degradation rates of MO and Rhb were 82.22% and 99.81%, respectively, after 30 min of open light. The results of experiments upon both zeta potential and radical quenching showed that ·OH and ·O2− were the main active radicals for dye degradation in our synergistic system. In addition, stability tests showed that the photocatalysts in the synergistic system still had good reusability. Therefore, the use of a synergistic system can effectively reduce the photogenerated electron-hole pair complexation rate, representing a significant improvement in both photocatalytic degradation and for stability levels.

The water environment is mostly polluted by expanded industrial advancements and growth, which directly liberates various toxic pollutants into the water streams. These emerging pollutants cause several hazardous health issues to humans, animals, and the ecosystem. Conventional treatment methodology faces different issues in the recognition and removal of toxins, such as expense, facile operation conditions, and the prerequisite of high maintenance. To overcome this issue, adsorption is viewed as one of the most encouraging innovations for the removal of pollutants. Recently, metal-organic frameworks (MOFs) have been considered to be efficiently adsorbent, because of their porosity, high surface area, fine-tunable metal clusters, and easy functional surface engineering properties. This Review concerns the recent examinations on MOFs as proficient material in the removal of toxic contaminants from wastewater. The adsorption mechanism of toxic pollutants removal using MOFs-based materials was critically reviewed and discussed. At last, challenges and the viewpoint for future advancement of MOFs is summarized.

“…Numerous contaminants, comprising chlorinated substances, organic dyes, heavy metals, surfactants, and inhibitory substances are present in the industrial effluent from the manufacturing sectors, which is the main cause of water pollution [ 19 , 20 , 21 ]. The residual organic dyes can enter the human body via the food chain and lead to a number of hazardous disorders, including mutation or cancer, skin irritability, permanent blindness, vomiting, hypertension, and gastritis [ 22 ].…”

High-Surface-Area-Activated Carbon Derived from Mango Peels and Seeds Wastes via Microwave-Induced ZnCl2 Activation for Adsorption of Methylene Blue Dye Molecules: Statistical Optimization and Mechanism

In this study, Mango (Mangifera indica) seeds (MS) and peels (MP) seeds mixed fruit wastes were employed as a renewable precursor to synthesize high-surface-area-activated carbon (MSMPAC) by using microwave-induced ZnCl2 activation. Thus, the applicability of MSMPAC was evaluated towards the removal of cationic dye (methylene blue, MB) from an aqueous environment. The key adsorption factors, namely A: MSMPAC dose (0.02–0.1 g), B: pH (4–10), and C: time (5–15 min), were inspected using the desirability function of the Box-Behnken design (BBD). Thus, the adsorption isotherm data were found to correspond well with the Langmuir model with a maximum adsorption capacity of (232.8 mg/g). Moreover, the adsorption kinetics were consistent with both pseudo-first-order and pseudo-second-order models. The spontaneous and endothermic nature of MB adsorption on the MSMPAC surface could be inferred from the negative ∆G° values and positive value of ∆H°, respectively. Various mechanisms namely electrostatic forces, pore filling, π-π stacking, and H-bonding govern MB adsorption by the MSMPAC. This study demonstrates the utility of MS and MP as renewable precursors to produce high-surface area MSMPAC with a potential application towards the removal of cationic organic dyes such as MB.
