Abstract
The present inventino relates to a quaternary ammonium salt compound for controlling sea-water algae flower and fresh water algae flower. Its advantages lie in that said compound can be independently used under the condition of low concentration (safely concentration for other living beings), and can kill red tide algae by above 90%. When it is mixed with flocculents of clay, etc. and used, the weight ratio of both them is 1:500-10000, and it can obviously raise effect for removing red tide algea, it is non-toxic, has no secondary pollution and its cost is low.
Description
The present invention relates to the application in administering seawater water bloom and fresh water water bloom of a kind of quaternary ammonium compound, particularly quaternary ammonium compound.
Quaternary ammonium compound can be expressed as R

-, R wherein
1, R
2, R

4Represent identical or different organic substituent respectively, X
-Represent the halogen ion.This class chemical combination is generally used for weaving, the aspects such as washing decontamination in papermaking, oil production, agricultural chemicals and the daily life, but Shang Weijian is used to administer the report of seawater water bloom and fresh water water bloom.At present, administering seawater water bloom and fresh water water bloom (Harmful algal blooms, HAB) aspect adopts flocculence, chemistry to kill method and ultrasonic disruption method etc. usually, wherein chemistry kill method and have that consumption is few, instant effect, advantage such as easy to operate, but existing chemical killing agent all has certain toxicity, has problems such as secondary pollution and ecologic effect, in addition, most of chemical killing agent cost is higher, makes this method be difficult to use.
The purpose of this invention is to provide a kind of quaternary ammonium compound of using in the method for administering seawater water bloom and fresh water water bloom, it can overcome the above-mentioned deficiency of prior art.
A kind of quaternary ammonium compound is characterized in that quaternary ammonium compound is used to administer seawater water bloom and fresh water water bloom.
A kind of composition is characterized in that said composition is made up of quaternary ammonium compound and flocculation agent, and both weight ratios are 1: 500-10000.
The invention has the advantages that lower concentration (biological to other is safe concentration) uses quaternary ammonium compound can kill the red tide algae down separately and reaches more than 90%.Mix when using with flocculation agent such as clay, can significantly improve the removal effect to the red tide algae such as clay, nontoxic, non-secondary pollution, and cost is also low.
Below by embodiment the present invention is described.
Embodiment 1
With the cetyl trimethylammonium bromide solution of deionized water preparation 250ppm, standby.Getting growth has the seawater of red tide algae (Heterosigma akashiwo) one liter (red tide plankton density reaches 10
8Individual/liter), add the standby quaternary ammonium salt solution of 2ml to it, make that the concentration of quaternary ammonium salt reaches 0.5ppm in the seawater, shake up.After 24 hours, kill red tide plankton 90%.
Used quaternary ammonium compound among the present invention, in its 4 organic substituents a long-chain fat hydrocarbon is arranged, its carbonatoms is 10-20, and all the other 3 substituent carbonatomss are 1-2, when administering seawater water bloom or fresh water water bloom with it, its concentration in seawater or fresh water is 0.1-5ppm.
Embodiment 2
Getting growth has the seawater of red tide algae (Heterosigma akashiwo) one liter (red tide plankton density is 10
8Individual/liter), to wherein adding the above-mentioned quaternary ammonium salt solution 1.5ml that concentration is 250ppm, make that the concentration of quaternary ammonium salt reaches 0.4ppm in the seawater, adding the flocculation agent sodium-ionized bentonite subsequently, to make its concentration be 0.5g/l, left standstill after shaking up 2 hours, the red tide plankton clearance is 100%.Flocculation agent sodium-ionized bentonite in the present embodiment can be used other kind clay (if you would take off soil, kaolin), loess or phosphate mineral instead.
Claims (4)
1, a kind of quaternary ammonium compound is characterized in that quaternary ammonium compound is used to administer seawater water bloom and fresh water water bloom.
2, a kind of composition is characterized in that said composition is made up of quaternary ammonium compound and flocculation agent, and both weight ratios are 1: 500-10000.
3, quaternary ammonium compound as claimed in claim 1, it is characterized in that in 4 organic substituents of this compound a long linear aliphatic hydrocarbon being arranged, its carbonatoms is 10-20, and all the other 3 substituent carbonatomss are 1-2, and it is being 0.1-5ppm by concentration in the water of administering.
4, composition as claimed in claim 2 is characterized in that described flocculation agent is clay, loess or phosphate mineral.
