Method for measuring anions and cations in amine liquid

The invention discloses a method for measuring anions and cations in an amine liquid, and relates to the technical field of chemical production. The method comprises the following steps of S1, sampling, carrying out sampling on an amine liquid storage tank through sampling equipment, installing a GPS positioner on the sampling equipment, and measuring specific longitude and latitude information of a sampling point through the GPS positioner; S2, pretreating an amine liquid sample; S3, carrying out cation determination, and performing determination by adopting an automatic potentiometric titration method; S4, carrying out anion determination, wherein an ion chromatograph method is adopted for determination; and S5, carrying out data processing, analyzing and processing the anion and cation detection data through a computer to obtain average data of the anion and cation content of the amine liquid. Spatial sampling is carried out on the amine liquid storage tank, samples at different positions of the amine liqu
