%X 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.
