Abstract
Penelitian ini membahas mengenai kinetika degradasi fotokatalitik malachite green dengan menggunakan katalis semikonduktor TiO2 dan O2/UV. Degradasi fotokatalitik malachite green mengikuti orde reaksi pseudo orde 0 dengan konsntanta laju reaksi 0,015 mol/L menit. Konsentrasi awal optimum adalah 20 ppm menunjukkan prosentase degradasi tertinggi sebesar 74,167% dengan penyinaran lampu UV 6 Watt selama 360 menit. Derajat keasaman (pH) larutan optimum berada pada pH 7 yaitu sebesar 60,021 % pewarna terdegradasi pada konsentrasi awal 40 ppm. Senyawa 4-N,N- dimetilaminobenzofenon merupakan hasil utama pada degradasi fotokatalitik malachite green.

This paper describes the kinetic study of malachite green photocatalytic degradation using TiO2 semiconductor catalyst and O2/UV. Photocatalytic degradation of malachite green was proposed as pseudo zero reaction order with velocity constant (k) 0,015 ppm/minute. Optimum innitial concentrasion was 20 ppm which malachite green could be degraded 74,167 % with 6 Watt UV lamp irradiation for 360 minutes. Significant effect was showed as pH solution changed. Optimum pH was 7 gave 60,021 % malachite green removal at innitial concentration 40 ppm. 4- N,N-dimetilaminobenzofenon was known as dominant product of malachite green photocatalytic degradation.
