“…8). From the Freundlich model, the parameter n [ 1, representing the degree of dependence of sorption with equilibrium concentration, indicates that europium is unfavorably adsorbed on Th 4 (PO 4 ) 4 P 2 O 7 in these experiment [34]. The europium sorption in phosphate medium, owning a lowest n and a highest k f value, presented strongest sorption intensity in the four kind medium.…”

“…The europium sorption in phosphate medium, owning a lowest n and a highest k f value, presented strongest sorption intensity in the four kind medium. The mean adsorption energy E (kJ/mol) obtained from D-R model is between 8 kJ/mol and 16 kJ/mol means that ion-exchange or chemisorption is the dominate factor [34]. It is same as the result from sorption-desorption isotherm.…”

“…Bradbury and Baeyens [30] studied the sorption behavior of Eu(III) on Na-and Ca-montmorillonite and proposed that bidentate complexes formed and cation exchange reactions occurred between the surface of the sorbent and Eu(III). Recent years, some new materials were used to study sorption of Eu(III) characteristics [31][32][33][34][35][36][37].…”

The sorption of Eu(III) on Th 4 (PO 4 ) 4 P 2 O 7 was studied under ambient conditions using the batch technique. The effects of pH, the concentrations of Eu(III) on Th 4 (PO 4 ) 4 P 2 O 7 sorption were investigated. The sorption characteristics of sulfate, phosphate and fulvic acid (FA) on Th 4 (PO 4 ) 4 P 2 O 7 was explored in the presence Eu(III). The results indicated that sorption of Eu(III) on Th 4 (PO 4 ) 4 P 2 O 7 was strongly affected by pH and the concentrations of Eu(III). Eu(III) sorption onto Th 4 (PO 4 ) 4 P 2 O 7 was greatly enhanced in FA and phosphate media than in KNO 3 . The Langmuir, Freundlich and D-R model were used to simulate the sorption isotherms of Eu(III) at four different medium. FA sorption isotherm can be described by Langmuir model in presence and absence of Eu(III) in solution.

Several adsorbents have been tried out by researchers to remove different pollutants from wastewater. However, the adverse effect of these biosorbents on the treated water and the possibility of leaching new pollutants to the treated water have not been investigated. A batch technique was employed to study this phenomenon. Three agricultural wastes namely sawdust, dates stones and palm fibers were investigated. The possible leaching of total dissolved solids (TDS) and organic compounds in the form of chemical oxygen demand (COD) from these substances to water were investigated. The effect of water pH and particle size of these biosorbents on the extent of the leaching process was studied. The results indicate high release of both TDS and COD for the three biosorbents. A COD value as high as 230 mg l -1 was obtained, while the highest TDS leached was 29 mg l -1. DS was found to have the highest leaching ability, followed by SD and PF. The highest leaching was obtained at high pH and small particle size of the adsorbent.
