Abstract

The invention discloses an automatic analyzer and a detection method for detecting ammonia nitrogen in environmental water. The automatic analyzer is characterized in that an injection pipe is connected with the A end of a multi-position distribution valve; the O end of the multi-position distribution valve is sequentially connected with a sampling ring and the A1 end of a first three-position valve; the B end of the multi-position distribution valve is connected with the A2 end of a first four-way valve; the C2 end of the first four-way valve is connected with the lower end of a micro distiller; the upper end of the distiller is connected with the D3 end of a second four-way valve; the C3 end of the second four-way valve is connected with the inlet of a condenser; the outlet of the condenser is connected with a sample collection needle of a sample collection tube through a first tubing mounted on a peristaltic pump; a first carrying bottle is connected with the B1 end of the first three-position valve; the B4 end of a second three-position valve is connected with an agent needle of the sample collection tube; a detection sample needle of the sample collection tube is connected with a detector through a second peristaltic pump; and the detector is connected with a computer through a data line. The automatic analyzer provided by the invention can realize automatic analysis, improve the detection accuracy and reduce discharge of waste liquid, thereby realizing automatic ammonia nitrogen monitoring in the environmental water.

Description

technical field [0001] The present invention relates to a full-automatic analyzer for ammonia nitrogen in environmental water and a method for detecting ammonia nitrogen in environmental water, in particular to an online distillation of environmental water samples with a micro still, adding reagents to a syringe, and photometric analysis to determine the total concentration of ammonia nitrogen in environmental water. An automatic analyzer and a method for detecting ammonia nitrogen in environmental water. Background technique [0002] At present, to measure ammonia nitrogen in water, for samples with many impurities and chromaticity interference, the method of distillation is mainly used to remove the interference. Most of the distillers currently used are 500ml distillation flasks. This method and instrument mainly have the following deficiencies: [0003] 1. Because manual operation is required, there are human errors, and the amount of reagents consumed each time is large...
