Abstract
The utility model provides a blowing device for quick determining sulphide content, which is used for the blowing pre-processing of the water sample of the sulfide. The utility model is provided with a silicone tube (2) which is communicated with a rotor flow meter (1) and a nine-way nitrogen tube (3) which is communicated with an H[2]S generation tube (6) via a silicone tube (4); an H[2]S absorbing tube (8) is communicated with the H[2]S generation tube via a silicone tube (7). The utility model is widely used for the determining of the monitoring method such as iodometric method, methylene blue colorimetric method, etc. The accuracy is high, the precision is high, and the relative error and the deviation are small than and equal to +-3; compared with the standard method, the blowing working ability is enhanced by more than 48 times. The utility model has the advantages of simple structure, reasonable structure, convenient operation and easy scouring.
Description
The utility model provides a kind of device of measuring sulfide content in the water sample, belongs to a kind of environmental protection aquatic monitoring apparatus.
Sulfide is must survey project in the water of national regulation and the effluent monitoring project.Usually the sulfide of being measured means the H of dissolving
2S and HS
-, S
=, and acid soluble metal sulfide.Contain multiple disturbing factors such as organism such as various suspensions, sediment, inorganics in the water sample, therefore, can not directly water sample be measured, must to water sample blow pre-service, could measure after eliminate disturbing.But, existing some sulfide blowning installation, complex structure not only, complex operation, time-consuming longer, and also the recovery is low, has directly influenced the accuracy and the work efficiency of monitoring result.
The purpose of this utility model provides a kind of blowning installation of fast measuring sulfide content, to improve the accuracy and the work efficiency of monitoring result.
The utility model is achieved in that nine logical nitrogen tube are connected together H by silicone tube and spinner-type flowmeter
2S generates pipe and communicates H by silicone tube with nine logical nitrogen tube
2The S absorption tube is by silicone tube and H
2S generates pipe and communicates.
Adopt the blowning installation of the fast measuring sulfide content of said structure, can be widely used in the air blowing pre-service of the above water sample of sulfide content 0.02mg/l, recovery of standard addition can reach 97～103%, relative error, relative deviation are all≤± 3%, accuracy, precision height, blown work efficient height can be finished the air blowing pre-service of 8 water samples in 5-10 minute, improve more than 48 times than standard method, save 1.8～60 times of nitrogen than original blowning installation.Simple and reasonable for structure, easy cleaning, not fragile, and can reduce investment outlay.
Below in conjunction with description of drawings structure of the present utility model and using method.
Fig. 1 is the front view of the utility model structure.Fig. 2 is its vertical view.
As shown in drawings, on the blowning installation of the fast measuring sulfide content of the utility model, nine logical nitrogen tube (3) are connected together H by silicone tube (2) and spinner-type flowmeter (1)
2S generates pipe (6) and communicates with nine logical nitrogen tube by silicone tube (4), outer control gas folder (5), the H of being equipped with of silicone tube (4)
2S absorption tube (8) is by silicone tube (7) and H
2S generates pipe and communicates.
H
2S generates pipe (6) and H
2S absorption tube (8) is placed in respectively in test tube rack (9) and the test tube rack (10).
Described nine logical nitrogen tube (3) also can pass to or nine pass to down for nine.The quantity of control gas folder (5) is identical with silicone tube (4) quantity.
During use, whether earlier logical nitrogen inspection has gas leakage, and adjusts control gas folder, makes each H
2S generates pipe nitrogen flow unanimity, closes source of the gas then.Toward H
2Add a certain amount of H in the S absorption tube
2The S absorption liquid is toward H
2S generates and adds sulfide water sample to be measured and appropriate amount of acid in the pipe, and close plug with the nitrogen flow rate of every pipe 0.1l/min, is ventilated after 5 to 10 minutes, closes source of the gas, and the air blowing absorption process can be finished.Can make H by iodimetric titration or to amino-xylene amine Spectrophotometry for Determination then
2Sulfide content in the S absorption tube.
H
2S generates pipe (6) and H
2The structure of S absorption tube (8) is respectively two bodys and is sleeved on together, and two pipe socket places carry out ground.
Nine logical nitrogen tube, H
2S generates pipe, H
2The S absorption tube is made by glass.
Claims (2)
1, the blowning installation of fast measuring sulfide content is characterized in that, nine logical nitrogen tube (3) are connected together H by silicone tube (2) and spinner-type flowmeter (1)
