Zusammenfassung:The invention relates to an organic trace element quality detection method, in particular to an organic trace element quality detection method based on a conductivity titration method, which comprises the following steps: S1, placing: placing an iron rack with a stirrer structure at a specified position, then placing an electronic scale at a position below the stirrer, and placing the electronic scale at a position below the stirrer; then placing the beaker on an electronic scale; s2, adding a to-be-detected solution; s3, mounting is carried out; s4, adding a titrating solution; s5, stirring; and S6, conductivity detection: detecting the conductivity of the solution through a conductivity meter, measuring the pH value of the solution through a pH meter, and performing computer-aided calculation to obtain the pH value of the solution. According to the method, different existence forms such as a chelating state, a complexing state and a dissociation state of the sample are judged according to extreme points, wh
