Penggunaan ZnO/zeolit sebagai katalis dalam degradasi tartrazin secara ozonolisis

An investigation on modification of natural zeolite with ZnO for the degradation tartrazine. In this study, as a semiconductor is modified into support to form ZnO/zeolite that can increase efficiency Further, formed catalyst was added tartrazine by determining variation in ozonolysis time, amount addition catalyst, and time. The results were determined UV-Vis spectrophotometer at 424 nm. result showed percentage obtained each degradation. resulted percent 20 ml concentration 15 mg/L using mg 56.80%, while 0.77 42.25%, 19.23 Zeolite 31.18%, all condition proceeded 40 minutes ozonolysis. Thus, indicates percentages It known very effective increasing Analysis compounds fourier-transform infrared spectroscopy (FTIR) after changes wavenumber there breaking bonds compounds.
