TY - JOUR TI - Solar photo-Fenton optimisation in treating carbofuran-contaminated water PB - Universidad Nacional de Colombia PY - 2012 issn 0120-5609. AB - Box-Benkhen design response-surface methodology was developed to optimise photo-Fenton degradation of carbofuran (C12H15NO3) 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 [H2O2] concentration and iron [Fe2+] 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 t30W = 15 min with 17.1 mg l-1 Fe2+ and 121.6 mg l-1 H2O2. Photo-Fenton degradation led to 76.7% mineralisation. Biodegradability during optimisation was evaluated by using the BOD5/COD ratio; this value increased from 0.04 at the beginning of the process to 0.52 in t30W = 20 min, thereby showing the effectiveness of using biological treatments KW - Foto-Fenton KW - Pesticidas KW - Diseño Box-Benkhen KW - Biodegradabilidad KW - Métodos de investigación en bioquímica KW - Biodiversity conservation UR - http://hdl.handle.net/10906/82340 ER -
