Description
Technical field
The utility model relates to a kind of laboratory research accessory system, particularly relates to a kind of Study system of simulating Ocean acidification.
Background technology
CO
2be one of topmost greenhouse gases that mankind's activity produces, and the mankind continue in air, input a large amount of CO by the burning of fossil fuel and other activities
2.The CO of ocean uptake
2alleviation global warming is played an important role, but it destroys the chemical balance of ocean self carbonate, causes seawater acidity to increase.This due to ocean uptake in air people be CO
2the seawater acidity caused increases process, is called as Ocean acidification (Ocean Acidification, OA).Compared with before the industrial revolution, when the pH mean value of surface seawater is from the industrial revolution 8.2 drop to current 8.1, according to Intergovernmental Panel on Climate Change (IPCC) prediction, to the end of this century, seawater pH value will reduce by 0.3 ~ 0.4 unit again, i.e. H in seawater
+concentration is by increase about 1 ~ 1.5 times, and by 2250, pH value can reduce by 0.7 unit again.
2003, this term first time of Ocean acidification (Ocean Acidification) appeared in " Nature " magazine.CO in air
2volume fraction continues to raise, and causes ocean uptake CO
2the amount of (sour gas) constantly increases, and seawater pH value declines, this by Atmospheric CO
2the process that volume fraction raises the seawater acidity increase caused is called as Ocean acidification.Since the industrial revolution, ocean approximately absorbs the carbonic acid gas of the anthropogenic discharge of 1/3rd, when making the pH mean value of surface seawater from the industrial revolution 8.2 drop to current 8.1, predict according to Intergovernmental Panel on Climate Change (IPCC), by 2100, therefore seawater pH mean value will decline about 0.3 ~ 0.4, to 7.8 or 7.9, till that time, when seawater acidity will start than the industrial revolution about large 100% ~ 150%.
Ocean acidification by the halobiontic survival and development of impact, and then has influence on the stable of marine ecosystems, also can have an impact to the marine economy of the mankind simultaneously.In view of Ocean acidification causes so large harm and domestic and international also relatively limited for Ocean acidification research at present to marine environment, the therefore now a kind of experimental technique that can study Ocean acidification of needs or experimental provision.At present, the method obtaining laboratory simulation seawater acidifying experiment both at home and abroad mainly contains pH and monitors in real time and carbonic acid gas (CO
2) dividing potential drop adjustment method.Wherein pH monitors by specific program in real time by calculator, pH supervising device and CO
2solution pressure valve connects, regulate with the automation realizing testing seawater pH value, although this method has full-automation, saves manpower, the advantage such as easy to operate, the foundation of the real-time monitoring system of pH needs to design special program, experimental facilities is complicated simultaneously, and therefore its expense is relatively high.And CO
2the method that dividing potential drop regulates mainly contains two kinds, and one is by pure CO
2directly pass into and cultivate in seawater, carry out closing after meeting the requirements of pH and cultivate, the method has the advantages such as simple, convenient, quick, but cannot ensure the stability of experimentation pH value.And another kind is by pure CO
2after gas and air mix by a certain percentage, pass into continuously cultivate seawater to realize acidulated condition, the method have can maintenance system pH value constant, advantage simple to operate, but need previously prepared different CO
2the gas of concentration, and need constantly to stir seawater in venting process, like this can to cultivate biological growth, grow and cause artificial mechanical damage.Therefore a kind of Novel laboratory simulated seawater acidizing device that can solve the problem or system is needed now.
Summary of the invention
