“…This suggests differences in the sorption mechanisms of triazine compounds with different substituent at the 6-position of triazine ring. This fi nding is in good agreement with differences in free energy changes reported for the sorption of chlorotriazines and methylthiotriazines in reference EURO-Soils (30).…”

This article compares the sorption behaviour of 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol, pentachlorophenol, chlorotriazine atrazine, methylthiotriazine ametryn, methoxytriazine atratone, hydroxyatrazine, and didelakylated atrazine in a topsoil and an aquifer sediment before and after removal of sorbent organic matter and in humic acid. Freundlich isotherm coeffi cients K f and 1/n and free energy change (∆G°) were calculated for all compounds in all sorbents. According to sorbent pH values, chlorophenolate anions and uncharged triazine species dominated in all sorption experiments with topsoil and aquifer sediment. In experiments with humic acid, chlorophenols, atrazine, and didealkylated atrazine existed almost completely as neutral species, whereas protonated species dominated for hydroxyatrazine, atratone, and ametryn. In addition to a hydrophobic partition, sorption of all compounds in native soil and sediment sorbents includes specifi c, more polar interactions, which greatly depend on sorbate acidity/ basicity, specifi c properties of the sorbent organic matter and of mineral surface, as well as on the system pH. A signifi cantly greater sorption intensity of all compounds in "organic-free" than in the native aquifer sediment confi rmed the importance and possible dominance of mineral surface in the sorption process. Sorption intensity of chlorophenol and triazine compounds in humic acid was closely related to compound hydrophobicity. Greater sorption of almost completely protonated hydroxyatrazine than of the more hydropohobic but uncharged atrazine indicated different humic acid reaction sites for two compounds and consequently different sorption mechanisms.

“…The groups present in humic substances are protonateddeprotonated, depending on the solution pH [22][23][24]. Extensive work has been reported in the literature focusing on the adsorption of atrazine on different types of soils [25][26][27][28][29], or on constituents of soil, including organic matter (SOM) or humic acids [30][31][32][33][34] and clay minerals [35][36][37]. In other reports, the interaction mechanisms between atrazine and SOM or clay minerals have been examined in detail.…”

“…On the other hand, chlorophenols are typical pollutants produced in a number of pharmaceutical, chemical, petrochemical and agricultural processes. Until now adsorption of some type of chlorophenols had been studied using coir pith carbon (Namasivayam and Kavitha 2003), modified activated carbon (Pakula et al 2005), euro-oils (Fingler et al 2004), iron oxides, titanium oxide and aluminum oxide (Bandara et al 2001), granular activated carbons (Jung et al 2001) and montmorillonite (Farkas and Dékány 2001) as an adsorbent. Pumice is relatively cheap than other adsorbents.…”

The adsorption of monochlorophenols (o-, m-, p-chlorophenol) on pumice, Zn/pumice and Cu/pumice has been studied through Fourier Transform Infrared (FTIR) Spectroscopy in transmission mode. The data show that after Zn and Cu were supported on pumice, the adsorption of 4-chlorophenol is characterized by the bands at 1591, 1494, 1092 and 824 cm(-1). Adsorption process occurred via metal cations on the surface of pumice. Metal oxides on pumice can mediate binding of p-chlorophenol.
