A low-cost detection device based on a flow injection pump and a spectrophotometer was developed for the automatic spectrophotometric detection of leather sweage in various sections of a tannery water plant. The equipment was computer controlled by a program written in Qt. The effects of reagent concentration, sample salinity, and foreign ion interference on the samples were investigated. The national standard method was used to judge the accuracy of the test, select the standard solution test method arbitration, and calculate the spiked recovery. A positive hexagonal carousel was set up in the device to place the standard liquid pool, into which the test liquid and standard color developer were pumped by peristaltic pump respectively, and the cuvette used a 1 cm quartz channel pool, which was pumped into the test after the sample finished color development. This device can be used for tanning production staff to quickly judge the effect of each chemical in the process and improve production efficiency.
