Embodiment 1

[0025] Embodiment 1: A kind of online monitoring analyzer of fluoride ion in water body

[0026] figure 1 A schematic diagram of the overall composition of the online fluoride ion monitoring analyzer of the present invention is given.

[0027]The fluoride ion online monitoring analyzer in the water body of this embodiment is mainly composed of a reagent rack 1, a manifold solenoid valve combination module 2, a peristaltic pump 3, a stirring detection pool module 4, a micro-diaphragm pump 5, a waste liquid bucket 6, and signal acquisition The control unit 7, the parameter setting control and analysis display unit 8, are assembled through the signal connection line and some corrosion-resistant hoses, corrosion-resistant hard tubes and corrosion-resistant fasteners in the following manner: the pure reagent rack 1 The reagents in the water reagent bottle A1, the water reagent bottle A2 to be tested, the ionic strength regulator reagent bottle A3, and the fluorine standard liquid ...

Embodiment 2

[0032] Embodiment 2 uses the fluoride ion online monitoring analyzer in embodiment 1 to detect the method for fluoride ion in water

[0033] (1) Preparation of standard reagents:

[0034] 1) Prepare fluorine standard solution: ①Weigh 0.2210g of sodium fluoride (NaF) dried at 105°C for 2 hours, dissolve in pure water, dilute to 100mL, store in a polyethylene bottle, and obtain 1.0mg / mL fluorine Sodium chloride standard stock solution 100mL;

[0035] ②Pipe 2.0mL of 1.0mg / mL sodium fluoride standard stock solution into a 1000mL volumetric flask, dilute to the mark with pure water to obtain 1000mL of 2.0mg / L fluoride standard solution, and transfer it to fluorine standard solution reagent bottle A4 for later use .

[0036] 2) Preparation of ionic strength regulator (TISAB):

[0037] Weigh 59g sodium chloride (NaCl), 3.48g trisodium citrate (Na3C6H5O7 5H2O) and 57mL glacial acetic acid (ρ 20 =1.06g / mL) in pure water, adjust the pH to 5.0-5.5 with sodium hydroxide solution, dilu...

Abstract

The invention discloses an on-line monitoring analyzer for fluorinion in water and detection method thereof, the method is characterized in that: by design and integral assembly innovation of a multi-branch plate solenoid valve combination module, a stirring and detection tank module, a signal acquisition control unit and a parameter setting control and analysis display unit, automatic operation of sensor signal acquisition, solenoid valve control, peristaltic pump control, stirring device control, waste liquid discharge, and result analysis, calculation and display, is implemented; preparation of high and low fluorine standard solutions and multi-step measurement can be automatically completed; and a condition that multi-devices are manually controlled for measuring in current detection is overcome. By technology integration and modularization design for the current test processes by a technical scheme provided by the invention, long-term, continuous, simple and rapid on-line monitoring on fluorinion in water can be easily implemented by apparatus for a non professional. The method has advantages of high result instantaneity, small reagent amount and low operation cost.

Description

technical field [0001] The invention belongs to the technical field of environmental protection detection, and in particular relates to an online monitoring analyzer for fluoride ions in water bodies and a detection method thereof. Background technique [0002] Fluorine is one of the trace elements closely related to human health. Fluorine in the human body is mainly concentrated in bones, teeth, nails and hair. Insufficient fluoride intake in the human body can easily cause dental caries; excessive intake can cause dental fluorosis and even skeletal fluorosis. Most of the fluoride in the human body is taken from daily drinking water, and a small part is taken from food and air. Fluorosis in many rural areas and impoverished mountainous areas in my country is mainly caused by high fluoride content in drinking water. Therefore, it is very important to carry out safety detection of fluoride ion concentration in drinking water. In addition, because fluoride is used in aluminum...
