“…In order to describe the mechanism of sulfamethazine sorption on the soil, the data obtained from the sorption experiments were fitted to the Linear isotherm (one-parameter model) (Liao et al, 2014;Białk-Bielińska et al, 2012;Hörsing et al, 2011;Goldberg, 2005), the Freundlich (Kim et al, 2012;Liu et al, 2011;Goldberg, 2005;Freundlich, 1906) and the Dubinin-Radushkevich isotherm (two-parameter models) (Chao et al, 2014;Zhang et al, 2011;Domínguez et al, 2011;Foo and Hameed, 2010). The equation and linearized form of these isotherm models are given in Supplementary information, Table S1.…”

In this paper, batch sorption of sulfamethazine on eight soil samples (six from Croatia and two from Bosnia and Hercegovina) with different organic matter contents ranging from 1.52 to 12.8% was investigated. The effects of various parameters such as agitation time, initial concentration, and ionic strength on the sulfamethazine sorption were studied. The experimental data were analysed using a one-parameter model, Linear isotherm, and two two-parameter models, the Freundlich and Dubinin-Radushkevich isotherms. The goodness of fit was measured using the linear regression and the determination coefficient (R(2)) value. Also, the equilibrium data of the two-parameter models were analysed using the residual root mean square error (RMSE), the sum of squares of errors (ERRSQ), and a composite fractional error function (HYBRID). Non-linear regression has better characteristics for analysing experimental data. The obtained sorption coefficients Kd (from 0.25 to 8.10 mL/g) and the Freundlich sorption coefficients KF (from 1.16 to 7.99 (μg/g)(mL/μg)(1/n)) exhibited quite low values, which indicated that sulfamethazine is weakly adsorbed on the evaluated soils, is highly mobile, and has a great potential to penetrate and pollute the ground water. The Dubinin-Radushkevich isotherm was used to estimate the apparent free energy of sorption.

“…Adsorption of NP was previously studied only for few types of inorganic carriers, and the results did not provide a clear idea about the retention mechanism of NP. For SiO 2 , the linear adsorption model fits best (Liao et al, 2014). The results of adsorption measurements performed on Na-montmorillonite (Nagasaki et al, 2004) suggest that adsorption of NP mainly takes place at the broken edges of the octahedral sheets of Al 2 O 3 , wherein the space between the aluminosilicate layers is not affected.…”

“…The irrigation district is located downstream of the alluvial fan of the Yongdinghe River, with an alternating lithology of sand and cohesive soil. The cohesive soil has a strong capacity for adsorption of NP and could reduce its mobility (Chen et al, 2011;Liao et al, 2014;Scrimshaw and Lester, 2002). The results for YGZ demonstrated that the infiltration of reclaimed water into the wetlands significantly affected the aquifer at a depth of 58 m, but had little influence at 80 m. The total NP GW at depths of 20,38,72 and 150 m at FHY (FHY20,FHY40,FHY72,and FHY150) was 366.8,629.5,365.5, and 0 ng/L (Fig.…”
