背景、目标和范围:Organoarsenical-containing动物饲料,促进经济增长和抗寄生虫主要是排泄不变,最终在附近的污水存储泻湖。早期作品记录了部分organoarsenicals转换,如3-nitro-4-hydroxyphenylarsonic酸(罗沙胂)更多的有毒的无机砷酸,[因为](V)和3-amino-4-hydroxyphenylarsonic酸(3-AHPAA)。不明罗沙胂代谢物使用液相色谱与电感耦合等离子体质谱法(LC / icp)也推断出从相应的质量平衡。早些时候批我们实验室实验表明有机金属(铜)复合物的存在期间相关罗沙胂降解实验。我们假设有机铜化合物复合体罗沙胂,调节其降解field-collected猪废水样本存储泻湖。本研究的目的是调查有机金属(铜)复合物的作用在罗沙胂降解猪废水悬浮液在有氧条件下,使用电喷雾电离质谱(ES-MS)。材料与方法:两个猪废水样品不同%固体含量和总可采铜浓度反应了500磅的罗沙胂在有氧条件下了16天。LC / icp和ES-MS用于形态分析、和表征metal-organoarsenical复合物的猪废水次级样本,分别。结果与讨论:一个有机铜罗沙胂代谢物被发现只有在high-Cu废水样本,表明在有氧条件下铜在罗沙胂降解中的作用。有机铜代谢物不是low-Cu废水样品中发现,因为罗沙胂不接受在有氧条件下退化甚至在16天。 CONCLUSIONS: Aerobic degradation of organoarsenicals (roxarsone) has not been documented before. Preliminary dataset from this study illustrates the direct and/or indirect association of particulate Cu in catalyzing roxarsone degradation under aerobic conditions in samples with high % solids content. RECOMMENDATIONS AND PERSPECTIVES: Concerns regarding the degradation of roxarsone in wastewater to the more toxic inorganic As may be partially linked to the presence of particulate Cu. The presence of Cu in wastewater-suspended particle surfaces has never been coupled before to organoarsenicals degradation reactions, thus, further studies are needed to elucidate the related reaction mechanisms and pathways. Water depth-dependent solid particle distribution profiles in wastewater storage lagoons could provide empirical evidence towards the design of effective degradation practices for nitrophenol-containing compounds, such as, organoarsenical-containing antibiotics, or explosive munitions compounds.
