摘　　要：研究了纳米金对硼氢化钠降解邻硝基苯胺的催化作用,考察了纳米金和硼氢化钠溶液浓度及体系酸度对邻硝基苯胺降解速率的影响。实验结果表明:中性条件下,0.20 mL 3.0 nmol/L的纳米金溶液和0.10 mL 5.0 mg/mL硼氢化钠共同作用下可使3.00 mL 0.1 mg/mL邻硝基苯胺20 min内降解89.41%。方法简单、快速,为邻硝基苯胺的处理提供了新的研究思路。In this paper,catalytic action of gold nanoparticles to the degradation of sodium borohydride solution to o-nitrophenylamine was studied,the concentration of gold nanoparticles and sodium borohydride solution and the acidity of the system on the degradation rate of o-nitroaniline were investigated.The experimental results showed that when 0.20 mL 3.0 nmol/L gold nanoparticles solution and 0.10 mL 5.0 mg/mL sodium borohydride solution were added into 3.00 mL 0.1 mg/mL neutral o-nitrophenylamine solution,the degradation efficiency of o-nitrophenylamine can get up to 89.41%in 20 min.This method is simple,rapid,and can provide a new idea for the abatement of nitrobenzene pollutants.
