Photo removal of imidacloprid from neonicotinoids using Bamboo vinegar

Although bamboo vinegar can be used as an antibiotic alternative on some bacterial communities due to its phenolic compounds, ketone and furfural ingredients, in this study the effects of increasing dilutions of bamboo vinegar to the photo-degradation of imidacloprid neonicotinoid was studied. The effects sun light and high-pressure mercury lamps on the photo-degradation efficiencies of imidacloprid pesticide were studied. Furthermore, the properties of initial imidacloprid dose, pH on the yields of imidacloprid were researched. The maximum photo-degradation yield was detected at 20 mg/L imidacloprid dose. 94% and 99.90% imidacloprid photo-degradation yields were detected when the bamboo vinegar diluted between 120 and 130 folds. High-pressure mercury lamp exhibited huge photo-degradation yields compared to sun light. The pH affects significantly the photodegradation yield of imidacloprid the photooxidation yield was low under acidic conditions while it was raised with increasing pH. Although bamboo vinegar exhibited a photo quenching property to on the imidacloprid neonicotinoid at low dilutions an improved photo-degradation yield was detected at high dilutions
