Determination of Chromium Ions with Perovskite Modified Glassy Carbon Electrode
The organic-inorganic-perovskite material(C2H7NPbBr3NCs)was prepared and used to modify the glass carbon electrode.By using the electrode,behavior of Cr3+was studied,and the concentration of Cr3+,solu-tion pH,pH of buffer solution and dosage of buffer solution were optimized.In Na2HPO4-C(OH)(COOH)(CH2COOH)2(citrate)buffer solution(pH=5.60),the concentration of Cr3+is linearly related to the current in the range of 1.0～8.0 µmol·L-1 with cyclic voltammetry.The modified electrode can be directly used for the determination of Cr3+in waste water,and has strong anti-interference ability.
