The invention relates to the technical field of
data acquisition, in particular to a
water quality detection method based on
ion chromatography, which comprises the following steps: selecting a sampling area, and sampling in the sampling area by using a
water quality sampler, the sampling comprises the following steps: stirring water in the sampling area, enabling the stirring depth to be 1 / 2 of the
water depth of the area, waiting for 8-14 minutes, and taking out the sampling area after the stirring depth is 1 / 2 of the
water depth of the area; collecting a
water source in the area by using the
water quality sampler to form a water quality sample; adding a proper amount of
persulfate radicals into the water quality sample, heating in a water bath to 70 DEG C, reacting for 0-4 hours, cooling, sampling, filtering through a filter membrane with the
pore diameter of 0.22 mu m, and directly injecting a sample after passing through a
chromatographic column, so as to obtain a solution to be detected; and constructing
ion chromatography conditions according to the solution to be detected, wherein the
ion chromatography conditions comprise cation conditions and anion conditions. According to the invention, the problems of long water quality detection period, low accuracy and high instrument and agent cost can be solved, and the water quality detection cost is reduced.
