Description
2, Disclosure of invention
(1) patent name
The measuring method of total sulfate in water and waste water
(2) technical field
The invention belongs to environmental area, a kind of quantitative analysis skill of total sulfate in gravimetric detemination water and waste water is related to
Art.
(3) background technique
The bottom deposit layer of water body can be diffused by the sulfate being discharged into ambient water, due to detesting for sedimentary
Oxygen environment conditional decision sulfate reducing bacteria will form certain advantage in this space, and along with sulfate reducing bacteria
Metabolic activity SO42-S can be converted into2-, these S2-, a part can be with most metal ions present in sedimentary together shape
In the sedimentary for precipitating and being deposited on the bottom of water body at the metal sulfide for being insoluble in water, another part then can Yu Shuizhong have
Machine object forms sulfurous organic compound, such as sulfuric acid, endangers specifically, water body excessively receives sulfate to generate following several respects to environment
Evil:
1；Accelerate the generation of methyl mercury
If containing a certain amount of mercury, the product S of sulfate reduction in water body2-Then sulphur can be formed in mercury present in water body
And mercury complex, and it is further converted to methyl mercury, it, can largely due to the presence in sulfate-reducing process
Accelerate the generation of methyl mercury.
2；Cause the necessary minor metallic element missing of water plant
In general, the normal growth of water plant be unable to do without certain minor metallic elements, in water bottom sedimentary sulfate
In the case that reduction process is active, the product S of sulfate reduction2-Generation metal sulfide can be combined heavy with most of metal ion
It forms sediment, aqueous minimum plant metallic element is caused to lack, the ecological balance of water body will be entirely destroyed.
3；Change the original ecological functions of water body
In the case where water body receives excessive sulfate, the sulfate-reducing process of water body lower layer space will become very
Active, product hydrogen sulfide generated has very strong toxicity, and the aquatic animals such as fishes and shrimps is caused to become extinct, and loses water body original
Ecological functions.
In recent years in water and waste water total sulfate measurement analysis, mostly use that State Environmental Protection Administration works out " water and
Effluent monitoring analysis method ", national standard " the measurement gravimetric method of GB11899-89 water quality sulfate ".It is cumbersome, it influences to divide
Analyse the accuracy of result, impact analysis speed.Using platinum crucible, platinum ware is expensive, at high cost.Make its application by
Certain limitation present invention more has advantage, on the basis of a large amount of analysis practices, this law is made to have quick, accurate, equipment

Between, reduce loss, improves accuracy.Production efficiency is improved, reagent consumption is reduced and cost of labor, method is easy to grasp
And result precision is high, can promote and apply in production.Simple using equipment, analysis process is short, has accurately and rapidly special
Point, the measurement analysis suitable for sulfate in water and waste water.
(4) content
Purpose: it is short to formulate a kind of operating process, at low cost, quickly, efficiently, it is accurate, stability is good, is easy to the measurement grasped
The analysis method of sulfate in water and waste water.
Technical solution:
The present invention is to measure the content of sulfate in water and waste water.
Specifically completed by following steps
Chloroazotic acid 10mL, 1-2 drop hydrofluoric acid are used in beaker.Dissolved samples, adjusting solution pH value with ammonium hydroxide (1+1) is 7,
(if there is precipitating is filtered with Medium speed filter paper, if do not precipitated without this step) be added barium chloride solution precipitated sulfur acid group from
Son, precipitating are stood overnight, and with quantitative filter paper at a slow speed, add paper pulp filtering, are cleaned with cold secondary washing beaker and with wiping stick, are washed precipitating
10 times,
Precipitating is placed in porcelain crucible, is carefully ashed in high temperature furnace, calcination 40 minutes under 800-850 degree, taking-up cooling,
Weighing.Constant weight.Calculated result.
(5) beneficial effect
1) quickly, efficiently, low cost: this method substantially reduces operating process, has saved drug, reduce detection at
This, improves production efficiency.
2) accurate, stable: to use this method, measurement result is stablized, and data are accurate.
(6) specific embodiment
