新型被动采样器的研制、验证和监测痕量有机污染物的应用
Development,validation and application of a novel passive sampler for monitoring trace organic pollutants
摘要
Abstract
Passive sampling technology,which emerged in the 1970s,has established itself as a critical method as it fulfills the requirements of environmental monitoring.The development of the ChemTRAP® passive sampler represents the integration of the foundational concepts of classic passive samplers with innovative microporous structural materials.This sampler stands out for its cost-efficiency,simplicity in deployment,and its integration with a tailored recovery system,facilitating both active and passive sampling studies.A 14-day indoor trial utilizing a custom-built sampling system was carried out to assess the adsorption kinetics of target substances onto the sampler and to verify the precision of detecting trace pollutants within aquatic environments.The sampling rate was quantified through controlled experiments,taking into account the accumulation of the target substance within the sampler,the concentration within the water body,and the duration of deployment.The findings revealed that over the deployment period,all six pollutants,including β-chloronaphthalene,atrazine,anthracene,fluorene,pyrene,and tris-o-cresyl phosphate(ToCP),displayed consistent linear adsorption characteristics,indicative of the kinetic adsorption process.The determined sampling rates(RS)fell within the range of 0.78 to 2.52 mL‧d-1,confirming the sampler's efficacy in assessing the concentration of target substances in water systems.关键词
