Özet

In present work, the sonochemical degradation of para nitrophenol (PNP) on raney alloy is described. Solutions of PNP at initial concentrations of 40, 50 and 75 ppm were prepared. 50%Al-50%Ni raney alloy (100 mg) was suspended in deionized water and sonicated for 15 min. Then, PNP (40, 50, 75 ppm) was added to the pre-activated alloy. The reaction mixture was sonicated for 15, 30 and 45 min at 30 degrees C. After sonication at different times, the concentration of para nitrophenol in the solution was determined by UV-visible spectrophotometer. For 40 ppm and the percentage of removal of para nitrophenol by Ni-Al alloy was found to be 95% after 30 min. (C) 2018 Elsevier B.V. All rights reserved.
