The optimum category of the four reagents in the synthesis of TRF was tested therefore on the removal of several pollutants linked to the chemical families of detergents, dyes and pharmaceuticals.The trials for these screening tests were performed over one weektime with a fixed charge of pollutant (100 mg L−1in the case ofdyes, 50 mg L−1in the cases of pharmaceuticals and detergents) ina total volume of 0.1 L with 20 mg of TRF for dye removal or 50 mgin the rest of the cases. Contact time was kept in 1 week as well and magnetic stirring was applied. The efficiency of such adsorbent inthe remediation of polluted wastewater is more than evident from Figs. 8–10.
