Solar photo-Fenton optimisation in treating carbofuran-contaminated water

Manuel Alejandro Hernández-Shek, Ana Cecilia Agudelo Henao, Claudia Mendoza Marín, Harlen Torres Castañeda

Abstract

Box-Benkhen design response-surface methodology was developed to optimise photo-Fenton degradation of carbofuran (C ₁₂H ₁₅NO ₃) by using a compound parabolic collector pilot plant. The four variables considered in Box-Benkhen design model included carbofuran degradation percentage, initial carbofuran concentration, hydrogen peroxide [H ₂O ₂] concentration and iron [Fe ²⁺] concentration. Degradation was monitored by using total organic carbon concentration and high-performance liquid chromatography. A 93.2 mg l ^-1 carbofuran concentration was completely degraded in t _30W= 15 min with 17.1 mg l ^-1 Fe ²⁺ and 121.6 mg l ^-1 H ₂O ₂. Photo-Fenton degradation led to 76.7% mineralisation. Biodegradability during optimisation was evaluated by using the BOD ₅/COD ratio; this value increased from 0.04 at the beginning of the process to 0.52 in t _30W= 20 min, thereby showing the effectiveness of using biological treatments.
