The concentration of organic carbon in solution was measured using an elemental analyzer (Shimadzu TOC 5050 /SSM 5000-A). Moreover, elemental analyses (Carbon, Nitrogen) on powder form samples were performed by using a Thermo Scientific Flash 2000 organic analyzer.
Fourier transform infrared (FTIR) measurements in the range 650-4000 cm -1 , were recorded using a Thermo Nicolet 6700 FT spectrometer equipped with a Deuterated Triglycine Sulfate (DTGS) detector and a Nicolet Continum microscope. The powder samples were spread over a NaCl window of the microscope. The analyzed sample area was a square of side 100 m chosen under the microscope 15X Infinity Reflechromat objective. The analyses were performed in transmission mode and each spectrum was the average of 256 scans collected at 2 cm -1 resolution.
The d 001 spacing's of the starting Mt clay mineral and after being in contact with organic pollutants were determined by the first 00l reflection from the X-rays patterns which were recorded in a conventional θ-θ Bragg-Brentano configuration by using a Thermo Electron ARL'XTRA diffractometer equipped with a Cu anode (CuK α1,2 = 1.5418 Å) coupled with a Si(Li) solid detector. The diffractograms on dry samples (100°C for 24 hours) were performed between 2 and 64° (2θ) with an angular and time steps of 0.04° and 10s respectively.
