Solar-powered photocatalysis in water purification: applications and commercialization challenges

Journal of environmental chemical engineering, Год журнала: 2024, Номер 12(3), С. 113073 - 113073

Опубликована: Май 14, 2024

Although heterogeneous photocatalysis has been recognized as a promising technology for decontaminating and disinfecting municipal industrial wastewater over the last few decades, it not yet successfully transitioned from laboratory-scale research to real-world applications. This limited progress is attributed inherent physicochemical properties of most photocatalytic materials available, which exhibit reduced photoefficiency under visible light irradiation, along with multiple engineering considerations. comprehensive review delves into intricate dynamics reactions kinetics, exploring several types reactors elucidating significance employed in treatment. critical survey systematically examines effectiveness different such titania, zinc oxide graphitic carbon nitride are commercially applied reactor systems. Understanding role these essential address challenges associated Furthermore, discussion extends beyond technical aspects encompass broader landscape hindering commercialization widespread adoption technologies. By critically evaluating challenges, minireview aims provide valuable insights researchers, engineers, policymakers seeking advance implement treatment on scale. synthesis knowledge consolidates current state field outlines future prospects overcoming barriers optimizing potential processes environmental remediation.

Morphological and Chemical Characteristics of Microplastics in Surface Water of the Vaal River, South Africa

Environmental Processes, Год журнала: 2024, Номер 11(1)

Опубликована: Март 1, 2024

Abstract Microplastics research in South Africa has focused on marine and coastal areas, with limited studies reporting microplastics freshwaters. To address this gap, we conducted study to investigate the presence, abundance, physical characteristics, chemical composition of surface water Vaal River, one most important freshwater systems Africa. Twenty-two samples were collected along 60 km middle part river using a 55 μm plankton net. Samples treated by acid digestion, MPs separated density separation. Physical identification was performed Nikon stereomicroscope, identified Raman spectroscopy. observed all 0.13 2.52 particles/m 3 concentrations. ranged size from 0.06 – 4.95 mm, more than 89% less 2 81% fragments (39%) fibers (42%). numerous colours, which green, black, blue dominant, representing 22%, 19%, 18%, respectively. Chemical analysis revealed polymer types as high-density polyethylene (HDPE), polypropylene (PP), low-density (LDPE). In addition, two colourants, pigment yellow 83 carbon detected. This provides new data microplastic occurrence characteristics River system offers baseline for future monitoring. Our findings confirm that is under real threat contamination, could impact its role significant Highlights • prevalent River. Fibrous, small-sized, coloured abundant. Polymers HDPE, LDPE, PP.

Case Studies in Chemical and Environmental Engineering, Год журнала: 2024, Номер 9, С. 100640 - 100640

Опубликована: Фев. 9, 2024

Microplastics (MPs) have emerged as persistent toxicants in the recent decade. MPs are reported to present different samples such soil, water, wastewater, and human including placenta, urine etc. Recent studies its presence drinking water. water is of concern research because associated with several toxicities animal models human. The presented review focused on understanding abundance, sources, detection, analysis, biotechnological approaches for degradation. paper discusses distribution, transport In addition, it identification advances biotechnological, metagenomics, system, synthetic biology Moreover, critically major challenges degradation Heterogeneity size shape makes difficult Most methods available analysis based dried analysis. Development liquid may bring a breakthrough research.
