mechanism which operates in both the dyes has been proposed and an identical related kinetic model was designed. The main interesting aspect of the present work pertains to the catalytic conversion of environmentally hazardous compounds into useful molecules; such are anthranilic acids and nitrobenzenes. Other special aspect related to catalytic activity of iron and potentially, iron catalyst accelerates
已经开发了一种有效的铁催化氧化降解方法,该方法是在碱性pH下使用聚合物负载的三溴化物试剂分别将对环境有害的偶氮染料和靛蓝染料分别选择性转化为硝基芳烃和氨基芳烃羧酸(邻氨基苯甲酸)。已开发出原位生成的和分离的(定义的)氯-铁(II)-吡啶-吡啶羧酸羧酸盐[Fe(tpy)(pic)Cl]催化剂体系,并发明了其催化功能用于降解过程。已筛选出不同的氮和氧配体以开发最佳催化剂体系,最后我们一起探索了吡啶2-羧酸和三联吡啶配体,发现是最佳的。值得注意的是,原位已经发现,所产生的和确定的催化剂体系对两种染料的氧化降解具有相似的催化活性是更有效的。结果,整个氧化降解过程都使用Fe(tpy)(pic)Cl催化剂体系进行,整个过程利用有效的催化方法选择性氧化偶氮和靛蓝的–NN–和–CC–键。染料分别。已经对该反应进行了详细的催化,机理和动力学研究。有趣的是,两种染料都在相同的动力学模式下以共同的氧化降解机理进
