Abstract
The invention relates to a method for rapidly and quantitatively measuring chlorine content.The method comprises the following steps that 1, a chlorine-containing sample is dissolved in water to prepare a sample solution; 2, a salpeter solution and a silver nitrate solution are prepared; 3, the salpeter solution and the silver nitrate solution are added into the sample solution, and the mixture is diluted with water and subjected to standing for a period of time; 4, turbidity reading is measured through a turbidity meter.The chlorine content in the sample can be rapidly and accurately measured.
Description
Technical field
A kind of method that the present invention relates to quantitative determination chlorinity.
Background technology
The raw and auxiliary materials such as stannous sulfate at present used in lead-acid accumulator, dividing plate, acid solution will carry out the mensuration of chloride content, wherein the current laboratory of the detection of chloride ion is usually and carries out detection analysis by optical colorimetry, silver nitrate solution is added in acid medium, silver ion generates the silver chloride suspension of white with chloride ion, the standard processed as simultaneously carries out visual comparison than turbid solution, the method can only qualitatively judge whether chlorinity in stannous sulfate reaches acceptability limit, and optical colorimetry measurement error is big, accuracy is low.Affected relatively big during finding chlorine measurement during actual stannous sulfate measures by humiture, and oxidizable solution turns to be yellow, impact is final judges.
Summary of the invention
In order to solve above-mentioned technical problem, a kind of method that the invention provides quantitative determination chlorinity, it is characterised in that comprise the following steps, it is soluble in water that (1) takes chloride sample, makes sample solution；(2) configuration salpeter solution, silver nitrate solution；(3) in sample solution, salpeter solution and silver nitrate solution are added, and dilute with water, place a period of time；(4) turbidity reads is measured with transmissometer.
Further, described sample is stannous sulfate, is dissolved in 20mL water, by 2mL salpeter solution acidified sample solution, adds 1mL silver nitrate (17g/L), is diluted to 100mL, shakes up placement 10 minutes, measures with transmissometer.
Method of the invention, it is possible to the chlorinity in rapid and accurate determination sample.
Accompanying drawing explanation
Fig. 1 is suspension turbidity and concentration relationship figure.
Detailed description of the invention
The invention will be further described for specific embodiment below in conjunction with the accompanying drawings.
The foundation of the method for quantitative determination chlorinity of the present invention is described as follows:
First configuration chloride standard solution 1mL solution chloride (CL) 0.010mg, concentration is 0.01mg/mL.Chlorine typical shelf solution 1mg/mL prepares: by benchmark sodium chloride calcination 1h in 550 DEG C of high temperature furnaces, places in vacuum desiccator and is cooled to room temperature, accurately weighs 1.6490g, it is dissolved in the pure water after boiling and cooling down, move in 1000mL brown volumetric flask, be diluted to scale, shake up.Chlorine standard solution 0.01mg/mL prepares: takes chlorine typical shelf solution 10mL in 1000mL brown volumetric flask, is diluted to scale with the pure water after boiling and cooling down, shakes up.Prepare chloride standard solution.
Secondly the relation of turbidity reads and cl concn is obtained.Take the volumetric flask of 6 100mL, pipette in the volumetric flask that 0mL, 1mL, 2mL, 3mL, 4mL, 5mL put into correspondence according to this from chlorine standard solution, it is separately added into 2mL salpeter solution (1+1), add 1mL silver nitrate solution (17g/L), with pure water dilution constant volume to 100mL scale, shake up gently.After placing 10 minutes standby.
With the above-mentioned 6 bottles of solution of transmissometer sequentially determining, read data as follows:
See Fig. 1, can show that suspension turbidity and concentration are good linear relationship from experimental data.
Finally, sample test.Weigh 1g sample stannous sulfate, be dissolved in 20mL water, by 2mL salpeter solution (1+1) acidified sample solution, add 1mL silver nitrate (17g/L), be diluted to 100mL, shake up placement 10 minutes, measure with transmissometer.According to linear relationship equation, sample cl concn can be directly obtained.
Other samples, dividing plate, sulphuric acid chlorine etc..Require differently configured chlorine standard solution according to difference, obtain different Haze curve.Cl concn can be obtained after measuring conversion with transmissometer by same method.
The inventive method can apply to the chloride content determination of the material affected without other particles, and the method can avoid the visual error that color exists, and measures simplicity quick and precisely, and the accuracy that can not only improve detection can also quantitative determine chlorinity.
