Aquatic contamination of diclofenac (DCF), an emergent non-steroidal anti-inflammatory drug (NSAIDs), can result in adverse effects to many ecosystems through biomagnification. Hence, introducing effective remediation techniques to sequester the pharmaceutical wastes is highly fundamental to prevent their accumulation in the environment. Generally, adsorption has been presented as a green and efficient approach. Herein, we report the characterization and application of the novel magnetic nanocomposite ([email protected]2O4) derived from cobalt-based ferrite (CoFe2O4) and graphene oxide (GO) for DCF adsorption. For the optimization procedure, the response surface methodology (RSM) was adopted to investigate the impacts of DCF concentration (1.6–18.4 mg/L), DCF dosage (0.08–0.92 g/L), and solution pH (2.6–9.4) to find the optimum conditions for DCF removal, at 10.5 mg/L, 0.74 g/L, and pH 4, respectively. For the adsorption experiments, the kinetic, isotherm, thermodynamic, and intraparticle diffusion models were systematically studied. Moreover, we have elucidated the role of functional groups on the surface of [email protected]2O4 in enhancing the adsorption of DCF drug. With good removal efficiency (up to 86.1%), high maximum adsorption capacity (32.4 mg/g), [email protected]2O4 can be a potential candidate to eliminate DCF drug from water. 相似文献
Little is known about personal exposure levels of black carbon (BC), a fraction of PM2.5, specifically in the transport microenvironments. In this study, real-time personal exposure to BC recorded by a portable microAeth AE51 was investigated in microenvironments in a round-trip from Hanoi (Vietnam) directly to Singapore. Personal exposure to BC was monitored in microenvironments at residential flat, in various surface modes of transport (taxi, bus, train), at the airports, and on the airplanes. The study found that personal exposure levels of BC in Singapore were higher than those in Hanoi for the same type of microenvironment in general for most of the microenvironments, except for smoking rooms. The highest exposures in each city were in smoking room in Noi Bai International Airport (NIA) and at bus station in Singapore, reached 98,709 ng/m3 and 44,513 ng/m3, respectively; the lowest personal exposure level was in-flight (approximately 250 ng/m3) for both trips. It is also remarkable that personal exposure to BC in indoor microenvironments was higher than outdoor levels.
Implications: Real-time personal exposure to BC was investigated in microenvironments in a round trip from Hanoi (Vietnam) directly to Singapore. BC personal exposure levels in Singapore were higher than those in Hanoi for the same type of microenvironment except for smoking rooms. Personal exposure to BC levels in indoor microenvironments was higher than in outdoor microenvironments. The highest levels of exposure were 98,709 ng/m3 in the smoking room at Noi Bai International Airport (Hanoi) and 44,513 ng/m3 at the bus station in Changi (Singapore). The lowest BC level was in-flight for both trips, at approximately 250 ng/m3. 相似文献
