Abstract—A three-layer artificial work (ANN) model oxides anic materials (OMs) are most important
was developed to predict the contributions of non-residual ponents in SSs [11, 12]. They play important roles in
ponents in surficial sediments (SSs) on atrazine (AT) controlling the adsorption anic and anic
adsorption based on 32 experimental sets obtained in a contaminants, with different contribution to the adsorption [13-
laboratory batch study, in which the inputs were selected as 15]. The various ponents may contribute
contents of Fe oxides, Mn oxides, organic materials (OMs), independently to the sorption anic pollutants; however,
ponent and the initial concentrations of AT, the interactions ponents may also take place [16]. To
output was set as the amount of AT adsorption onto SSs. The date, the studies on adsorption of the herbicides in SSs
performance of the BP ANN model was assessed through ponents are rarely reported, and the adsorption
