Flower-like AuPtPd-Fe3O4 new nanohybrid prepared through a scalable synthetic approach was tested for the effective and simultaneous removal of Humic Acids and Cr (VI). Field emission scanning electron microscopy (FESEM) equipped with an energy dispersive X-ray (EDX) probe, X-ray diffractometer (XRD) and thermogravimetric analysis (TG-DTG) were used for characterization. The nanocatalyst, at the end of the preparation process, results dispersible in water. Calibration equations were plotted for the removal evaluation of Cr(VI) and Humic Acids in water samples. Electrochemical tests were carried out at pH 3.0 and 30 mA. Humic Acids were highly mineralized with TOC removal efficiency of 95%. In 3 h, 99 % of total Cr was removed.
