摘 要本文以石墨化羧基碳纳米管为研究对象，锦鲫为受试对象，采用半静态染毒方法，分析暴露在不同浓度(10mg/kg、100mg/kg)的石墨化羧基碳纳米管溶液在 7、14、30 天后鱼体肝脏中蛋白质浓度、SOD 活性和 CAT 活性等指标，探讨其潜在的致毒机制。实验可得：染毒暴露时间的增加，不管是 10mg/kg 低浓度组还是 100mg/kg 高浓度组的 SOD 活性都呈现出上升趋势，机体产生氧化应激反应，对外界产生抵御能力；而对 CAT 活性都是呈显著性的降低，CAT 活性受到抑制，使锦鲫的肝脏失去调节能力，直到抗氧化防御系统受到损伤。关键词：石墨化羧基碳纳米管；锦鲫；SOD；CAT；毒性效应AbstractThis paper studied the protein concentration, SOD activity and CAT activity of graphitic carboxyl carbon nanotube solution exposed to different concentrations (10 mg/kg、100mg/kg) in the liver of fish after 7,14 and 30 days. The results showed that the SOD activity of 10 mg/kg low concentration group or 100 high concentration group showed an increasing trend, and the body produced oxidative stress reaction and the ability to resist the outside world. and the CAT activity was significantly decreased, and the CAT activity was inhibited, which made the liver of crucian carp lose its regulating ability until the antioxidant defense system was damaged.Keywords ： graphitic carboxyl carbon nanotubes; Carassius auratus; SOD;CAT; toxicity effect目 录1 引言.............................................................................................................................11.1 碳纳米管的概述..................................................11.2 碳纳米管的分类......................................................................................................11.3 碳纳米管的制备方法及其特点..............................................................................21.3.1 电弧放电法...........................................................................................................21.3.2 催化裂解法........
