| Abstract: | A novel and convenient method was presented for the determination of acetamiprid, which was based upon sequential perturbation of Ce (Ⅳ)-catalyzed belousov-zhabotinsky (B-Z) oscillating system with different amounts of acetamiprid using a continuous-flow stirred tank reactor (CSTR). The results showed that change in oscillating amplitude was linearly proportional and change in oscillating period was following a second-order polynomial to the concentration of acetamiprid in the range of 4.80×10~(-5) to 2.0×10~(-4) , with the regression coefficient of 0.999 5 and 0.997 6, respectively, the lowest detection limit was 5.0×10~(-7) mol·L~(-1). On this basis, the method for the determination of acetamiprid was established. |
