“…Once more, the kinetic scheme corresponding to the 24 stages of reaction can be assembled (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) that describe the decomposition of ozone to include the generation of hydroxyl radicals, and 21-26 corresponding to the interaction of 2,4-D, 2,4-DCP and 2-CHQ with molecular ozone and OH radicals, respectively) and solve the corresponding mass balances for the species involved.…”

“…Isoproturon (25 mg L −1 ) was degraded by homogeneous and heterogeneous photo-Fenton and it was found that iron pillared laponide-RD used as catalyst favored the mineralization by 10% (Bobu et al, 2007). Combining a biological system with solar photo-Fenton in a pilot scale compound parabolic collector (CPC) plant, diuron was successfully removed with a mineralization of approximately 80% in both simulated and real industrial wastewaters, using 9.4 mg L − 1 of Fe 2+ and 72 mg L − 1 of H2O2 (Mendoza- Marin et al, 2010). Effluents of the secondary treatment from a municipal WWTP contaminated with diuron and diclofenac at ng L − 1 levels were treated by photo-Fenton in a pilot CPC plant, using 5 mg L −1 of Fe 2+ and 50 mg L −1 of H2O2, and an overall contamination reduction of 97% was obtained in 50 min (Klamerth et al, 2013).…”

“…Solo en el Valle del Cauca, donde se llevó a cabo este estudio, se emplean alrededor de 63,000 toneladas métricas (TM) anuales de pesticidas aplicados a los cultivos de caña de azúcar (Asocaña 2010). El lavado de los envases y contenedores empleados en la aspersión de cultivos es una de las formas más comunes de contaminar el agua con estas sustancias (Mendoza-Marín et al 2010).…”

“…Sin embargo, la mayor desventaja que presenta la aplicación de la fotocatálisis heterogénea son sus elevados costos de operación al compararlos con los tratamientos biológicos. Por consiguiente, se ha planteado la oxidación parcial de los contaminantes mediante fotocatálisis heterogénea como tratamiento primario, con el objeto de transformarlos en intermediarios biocompatibles para después someterlos a tratamiento biológico, lo que resulta ser mucho más económico que las tecnologías convencionales para tratamiento de aguas (Mendoza-Marín et al 2010, Sarria y Pulgarín 2003. En este punto se evidencia el potencial del uso de humedales artificiales como alternativa eficiente, siendo empleados en el tratamiento de efluentes secundarios para reducir los componentes orgánicos, donde los residuos son tratados por microrganismos unidos a la superficie del medio y a las raíces de las plantas (Sauter y Leonard 1997).…”
