Abstract:
... The Bohart–Adams model has been one of the most widely used breakthrough models for the modeling of dynamic adsorption behaviors of water pollutants in a fixed-bed column. However, the fitting quality was often questioned by many researchers when the Bohart–Adams model was correlated with the experimental data. Recently, Chu (2020) discussed the two simplified forms of the Bohart–Adams model and t ...

Abstract:
... In this study, the original Bohart-Adams model was employed to analyze the experimental data of 17α-ethinylestradiol (EE2) separation in lab-scale anthracite columns with low initial concentration. Besides, the assumptions for the simplified Bohart-Adams model were calculated and discussed. The results revealed that the breakthrough curves of EE2 separation in anthracite columns under different co ...

Abstract:
... Microfibres are one of the most ubiquitous particulate pollutants, occurring in all environmental compartments. They are often assumed to be microplastics, but include natural as well as synthetic textile fibres and are perhaps best treated as a separate class of pollutants given the challenges they pose in terms of identification and contamination. Microfibres have been largely ignored by traditi ...

Abstract:
... A number of cities have developed an elevated walkway network within street canyons in order to alleviate pedestrian congestion. Naively one may expect lower pollutant concentrations inside elevated walkways, on account of the increased distance from traffic-related emissions, but this hypothesis has received little critical attention. The primary objective of this study is to determine whether pe ...

Abstract:
... The concentrations of a pollutant in people or in the environment are often changing as a function of time. In many cases, this rate of change may be relatively constant as a function of time; thus, first-order kinetics can be applied to these data. In other cases, the rate at which the concentrations of a pollutant are changing may be different before and after some event, for example before and ...
