Photocatalytic Degradation of the Insecticide Acetamiprid on TiO2 Catalyst

O trabalho está relacionado com a degradação fotocatalítica da acetamipride, uma base piridínica amplamente utilizada em inseticida neonicotinóides, em suspensões aquosas de O 2 /TiO 2 irradiada por UV. A taxa de degradação foi estudada por HPLC/DAD e espectrofotometria UV. Verificou-se que a reação é de pseudo-primeira ordem, no intervalo de concentração de (0,5-2,0 mg cm). A análise de RMN de...

UV/TiO2 photocatalytic degradation of xanthene dyes.

UV/titanium dioxide (TiO(2)) degradation of two xanthene dyes, erythrosine B (Ery) and eosin Y (Eos), was studied in a photocatalytic reactor. Photocatalysis was able to degrade 98% of Ery and 73% of Eos and led to 65% of chemical oxygen demand removal. Experiments in buffered solutions at different initial pH values reveal the pH dependence of the process, with better results obtained under ac...

Photocatalytic degradation of pyridine in water solution using ZnO as an alternative catalyst to TiO2

The degradation of pyridine, widely used in the synthesis of vitamins, drugs, rubber chemicals, herbicides and pesticides, can be photocatalyzed by semiconductor catalysts. Since zinc oxide promotes faster pyridine photocatalytic oxidation reactions than TiO2, the former appears to be a suitable alternative to TiO2 for water treatment contaminated with pyridine. The photodegradation efficiency ...

The Photocatalytic Kinetics of the Methyl Orange Degradation in the Aqueous Suspension of Irradiated TiO2

Background: In the present study, the photocatalytic (TiO2/UV) batch process has been used for the methyl orange (MO) degradation. Methods: In the catalyst range from 0.25 to 1.5 g/L, the optimum concentration of TiO2 was found to be 0.5 g/L. The kinetic behavior of MO degradation has been evaluated using the non-linear form of pseudo-first order and pseudo-second order models. Results: The g...
