本文以长链溴化S—烷基双硫腙衍生物为载体制备了邻硝基苯酚阴离子电极和对硝基苯酚阴离子电极,建立同时测定邻硝基苯酚和对硝基苯酚的方法,邻硝基苯酚的线性检测范围为5×10~(-3)—3×10~(-5)mol/L,检测下限为9×10~(-6)mol/L;对硝基苯酚的线性检测范围为5×10~3—4×10~(-5)mol/L,检测下限为2×10~(-5)mol/L。
In this paper, ortho-nitrophenol anion and p-nitrophenol anion were prepared by using long-chain brominated S-alkyl dithizone derivatives as carrier. A method for the simultaneous determination of o-nitrophenol and p-nitrophenol was established. The linear range of phenol was 5 × 10 -3 -3 × 10 -5 mol / L, and the detection limit was 9 × 10 -6 mol / L. The linearity of p-nitrophenol The range is 5 × 10 ~ 3-4 × 10 ~ (-5) mol / L, the detection limit is 2 × 10 ~ (-5) mol / L.
