Penggunaan ZnO/Zeolit Sebagai Katalis Dalam Degradasi Tartrazin Secara Ozonolisis

An investigation on modification of natural zeolite with ZnO for the degradation of tartrazine. In this study, ZnO as a semiconductor is modified into a natural zeolite as support to form ZnO/zeolite that can increase the efficiency degradation of tartrazine. Further, the formed catalyst was added t...
