Abstract
The invention belongs to the processing method that purification of water quality is handled, it is under temperature is 30 ℃-60 ℃ condition, adopts triiodide deionized water solution and strongly basic anion exchange resin, and the contact reacts that circulates forms stable and water-insoluble triiodo-compound.The sterilant that the present invention is made, when contacting with bacterium, killed bacterium can not adhere on the resin, can pass through resin layer at an easy rate, and the iodide amount in the importing water, be no more than pharmacological safe level, can play complete sterilization to serious pollution water quality.Its preparation method is simple, can life-time service.
Description
The invention belongs to the processing method that purification of water quality is handled.
At present, the water conditioning method of extensive employing is the plain treatment process of chlorine, and it is effectively in large-scale water conditioning, but does not satisfy people's daily life demand.Along with sharply increasing of population, the pollution aspect feedwater also increases thereupon, we can say that not having contaminated water resources is seldom.General treatment process is often residual certain density chlorine element, can cause being detrimental to health.Therefore, people wait in expectation can sterilization, again human body is not had the water sterilization sterilant of undesirable action.
The purpose of this invention is to provide does not a kind ofly have undesirable action to human body, the compounding process of long-acting water germicide.
The present invention realizes by following measure:
Be under 30 ℃-60 ℃ the condition, to adopt triiodide deionized water solution and strongly basic anion exchange resin in temperature, the contact reacts that circulates forms stable and water-insoluble triiodo-compound;
Reaction mechanism is as follows:
The sterilant that the present invention is made, when contacting with bacterium, killed bacterium can not adhere on the resin, can pass through resin layer at an easy rate, and the iodide amount in the importing water, be no more than pharmacological safe level, can play complete sterilization to serious pollution water quality.Water through this method sterilization and disinfection can needn't be handled directly as tap water again.Its preparation method is simple, can life-time service.
Strongly basic anion exchange resin of the present invention is a quaternary amine base anionite-exchange resin.But this reaction intermittent type carries out or carries out continuously, and the resin that is reacted is separated from solution by filtration or centrifugation.This triiodo-compound bonded triiodide ion itself forms split pole again, promptly
, the triiodo end is positively charged, and positive charge has just had sucking action to electronegative bacterium, when bacterium and bonded I
-
3Ion intersects when contacting, then I
-
3Ion just destroys the cytolemma of bacterium, causes bacterium death.Experiment shows, is not contained the I of bacteriocidal concentration in the filterable water
2, but the direct contact sterilization of cell walls of iodine and bacterium in the triiodide.When triiodide deionized water solution and quaternary amine base anionite-exchange resin, circulation contact reacts 10-14 hour, stopped reaction.Regain circulation fluid and wash with liquor kalii iodide, and then use distilled water wash, effluent liquid is with till cadmium iodide-the starch reagent test is negative.
Embodiment:
In the water of 100 parts of weight, the dissolving potassiumiodide of 5.1 parts of weight and the iodine of 7.8 parts of weight are mixed with the triiodide aqueous solution, and make this solution by 10 hours lentamente by the quaternary amine base anionite-exchange resin glass column of 10 parts of weight is housed.Then, with the potassium iodide aqueous solution washing, using distilled water wash again, is the starch reagent test with cadmium iodide at last.Adding 1 milliliter of cadmium iodide in the processing water sample of 20ml is starch reagent, as the test (not having cyan) that is negative just illustrates method according to the invention.With product seasoning or centrifugal drying.At this moment, whole technological process finishes, and water germicide is made.
This sterilant belongs to the contact sterilization, and concrete using method is as follows, and sterilant is packed in the container, and water to be processed flows into from an end of container, and the other end flows out, and can obtain sterilized water.
Claims (4)
1, a kind of preparation method of water germicide is characterized in that adopting triiodide deionized water solution and strongly basic anion exchange resin under temperature is 30 ℃-60 ℃ condition, and the contact reacts that circulates forms stable and water-insoluble triiodo-compound;
Reaction mechanism is as follows:
2,, it is characterized in that strongly basic anion exchange resin of the present invention is a quaternary amine base anionite-exchange resin according to the described preparation method of claim 1.
3, according to the described preparation method of claim 1, but the contact reacts intermittent type that it is characterized in that circulating carry out or carry out continuously, the resin that is reacted is by filtering or centrifugation is separated from solution.
4,, it is characterized in that when triiodide deionized water solution and quaternary amine base anionite-exchange resin circulation contact reacts 10-14 hour, stopped reaction according to the described preparation method of claim 1.
