Wastewater contains many organic and inorganic pollutants discharging them into received waters leads to serious environmental problems. The wastewater that is produced from various industries a noticeable amount of dyes; heavy metals metalloids this has remained one the major problems facing public health. Unfortunately, conventional remediation process unable remove dyes completely. One widely used water treatment technologies biosorption, biosorbents are considered be an emerging green, cost-effective, efficient alternative. Therefore, search for locally or regionally available biomasses metals/metalloids removal gained rapid attention. Methylene blue, Crystal violet, Reactive black 5, Congo red; Cd, Cr, Cu, Pb, Hg, Ni, Zn; As were selected as examples dyes, metals, metalloids, respectively, In regard, comprehensive understanding biosorption capability different necessary know how they can contaminants in wastewater. Biosorption ion exchange, complexation, coordination process. Besides, recent advances biomaterials-based approaches with several provide backdrop future research have been reviewed. This beneficial developing more effective eliminate contaminants, thus bridging gap between laboratory results industrial use. crustacean shells, algae, chitosan most biosorbents. These serve good alternatives synthetic materials

Toxic heavy metal ions contamination in water and their sustainable reduction by eco-friendly methods: isotherms, thermodynamics and kinetics study

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Март 31, 2024

Abstract Heavy metal ions can be introduced into the water through several point and non-point sources including leather industry, coal mining, agriculture activity domestic waste. Regrettably, these toxic heavy metals may pose a threat to both humans animals, particularly when they infiltrate soil. poisoning lead many health complications, such as liver renal dysfunction, dermatological difficulties, potentially even malignancies. To mitigate risk of ion exposure it is imperative extract them from places that have been polluted. Several conventional methods exchange, reverse osmosis, ultrafiltration, membrane filtration chemical precipitation used for removal ions. However, high operation costs generate secondary pollutants during treatment. Biosorption an alternative approach eliminating involves employing eco-friendly cost-effective biomass. This review focused on contamination in water, biosorption mathematical modeling explain behaviour adsorption. helpful researchers design wastewater treatment plants sustainable

Due to the growing concerns about pharmaceutical contamination and its devastating impact on economy health of humans environment, developing efficient approaches for removing such contaminants has become essential. Adsorption is a cost-effective technique pollutants. Thus, in this work, banana peels as agro-industrial waste were utilized synthesizing activated carbon pharmaceuticals, namely amoxicillin carbamazepine from different water matrices. The chemically by phosphoric acid (H3PO4) was carbonized at temperatures 350 °C, 450 °C 550 °C. material characterized several techniques scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared (FTIR), Boehm titration, point zero charge (pHPZC), BET surface area (SBET), proximate ultimate analyses, powder diffraction (XRD), thermos-gravimetric analysis (TGA). SEM peel (BPAC) depicted semi-regular heterogeneous morphology, an abundance pores diverse forms sizes. titration revealed increase amounts acidic groups 0.711 mmol/g due activation H3PO4. FTIR recorded peaks suggesting significant modifications spectroscopic characteristics BPAC successful adsorption pollutant molecules. pHpzc calculated be 5.005. SBET dramatically increased 911.59 m2/g after activation. optimum conditions 25 materials dosage 1.2 g/L, saturation time 120 min, pollutants mixture mg/L, pH 5. Langmuir exhibits slightly better fit than Freundlich low value residual sum squares (SSE) data fitted pseudo-second-order kinetic. Furthermore, efficacy eliminating pharmaceuticals Milli Q water, lake wastewater successfully investigated over seven cycles. results present work highlighted potential usage organic micropollutants while exhibiting sustainable management waste.
