PENGGUNAAN KATALIS ZnO-H2O2 UNTUK DEGRADASI ZAT WARNA RHODAMIN B DAN ALIZARIN-S
ABSTRACT: The textile industry
produce colored waste liquid that can contaminate the line water and its populations.
A number of dyes are using in textile industry processes such as rhodamine-B
and alizarine-S. Both of dyes are toxic for human life. In order to reduce the
concentration that dyes is used the sonolysis method which have good efficiency
and effective to degrade this pollutants. Sonolysis was performed using an
ultrasound energy at 47 kHz. Catalyst ZnO is used to get better degradation.
Rhodamine-B 2mg/L with 0.3 g ZnO addition, pH 5, temperature 40°C get 35.44% degradation
after 60 minutes. If we used 3 mL H2O2 30% in the same condition the
degradation up to 42.67% and with the combination of 0.3 g ZnO - 3 mL H2O2 as
catalysts it got 91.99% after 90 minutes. Alizarine-S 20 mg/L with 0.5 g ZnO
addition, pH 5, temperature 50°C was degraded up to 86.45% after 35 minutes.
Furthermore, the degradation reached 95.79% if it used 0.5 g ZnO and 25mL H2O2
30% at pH 5 and temperature 50°C after 35 minutes sonolysis.
