Using of nanomaterial's TiO2 and TiO2@SBA-15 for photo catalytic degradation of malachite green

Malachite green is used as a fungicide, bactericide and parasitic ide in the aquaculture industry, which is influenced on the environment as a pollutant .In this study, the using nano-photocatalysts TiO2@SBA-15 and TiO2 they were developed for efficient photodegradation of malachite green. This Absorbents is Eco-friendly And the have high performance in between of the nano-adsorbents. The used nano-photocatalysts was evaluated by the decomposition of malachite green as a model organic pollutant under UV light irradiation. Effects of various process parameters including adsorbent dosage (40, 100, 200, 400), contact time (240 min), initial pH (4, 7, 10) of the solution and initial Malachite green concentration (10, 20, 30) were investigated under batch adsorption system. The results showed that the optimal conditions of removal percentage of TiO2@SBA-15 (98%) accrued at initial concentration of 10 mg/l, adsorbent dosage of 200 mg/l and solution pH of 10. the TiO2@SBA-15 nanoparticles removal rate of 98% in 90 minutes performed better than the TiO2 nanoparticles removal rate of 60% in 240 minutes.
