Abstract:
With the increasing number of food safety problems caused by the abusing and misusing of plant hormones, it will be increasingly important to strengthen the trace detection of plant hormones in foods. In this study, benzyl methacrylate_methyl methacrylate_based amphiphilic polymer micelles were prepared, and a method for trace determination of five plant hormones was established by using these micelles. This method was rapid, sensitive and reproducible. Through optimization, the best experimental conditions were obtained as follows: 2 g/L polymer micelles, 50 mmol/L NaOH_H3BO3 buffer (pH 9. 2), 15 kV running voltage. Based on this novel method, naphthalene acetic acid in the solution of rooting powder was determined.
