Activated Carbon Can Really "Suck" So?

Players who play sea tanks all know that maintaining a perfectly functioning sea tank takes a lot of effort because there are not only beautiful creatures in it but also various unexpected situations, sometimes the water quality is suddenly muddy or in the water, body Adding other things by mistake will cause us headaches. In many cases, we will choose to use an artifact to deal with these problems urgently. Of course, it is activated carbon.

But Activated Carbon can really cope with various situations, can anything be sucked? What are its adsorption range and adsorption effect? Then we will discuss with you this issue.

First, activated carbon will adsorb copper ions, which is known to many aquarists, so many aquarists who have finished medicine will use it to remove excess drugs. The atomic weight of copper ions is 63.5, but the molecular weights of no3 and po4 are 62 and 95, respectively. 

Some fish friends have done experiments and soaked no3 at a concentration of 50mg/l in a relatively sufficient amount of new activated carbon, and found that no3 has not decreased much (the decrease may be due to dilution with water in activated carbon), the atomic weight is small The potassium will be adsorbed, but the no3 with a large molecular weight is not adsorbed.

What is the range of Dates Activated Carbon adsorption? Is it determined by molecular weight, or are there other judgment criteria? Let’s take a look at the Activated Carbon Manufacturer.

In fact, the adsorption of activated carbon can be divided into physical adsorption and chemical adsorption. Activated carbon is a substance with a porous structure. These porous structures provide it with a large amount of surface area, making it very easy to absorb and collect impurities.

Just like having a magnetic force, all molecules have mutual attraction, and activated carbon is no exception. A large number of molecules on the pore wall of activated carbon can generate a strong gravitational force, attracting some impurities in the water to the pore size.

But we need to pay attention that the diameter of this adsorbed impurity molecules must be smaller than the pore size of activated carbon, which is why there are so many different types of activated carbon on the market.

In addition to physical adsorption, there is also chemical adsorption. The chemical reaction usually occurs on the surface of activated carbon. This is because the activated carbon component is not just carbon atoms. The main elements in it are CHONPS, which form functional groups on carbon atoms. It is negatively charged, so it can adsorb some positively charged ions (such as heavy metals), but it cannot be adsorbed when it encounters negatively charged ions (nitrate, phosphate).

Therefore, the adsorption effect of activated carbon on some copper drugs is good, and most of the drugs that are misused or wrongly used, we can use activated carbon for emergency treatment, and nutrients, everyone still needs to change the water and adjust the feeding, slow Slow to improve the state of the sea tank.

In the process of using activated carbon, we need to pay attention to several points.

1. Before using the new activated carbon, more or less toner will fall, so we better rinse it with pure water before using it

2. Activated carbon needs to be replaced regularly, it is best to change it once a month because the adsorption of activated carbon has an upper limit, if the adsorption is full, the replacement may not occur, and even harmful substances may be released

3. Do not use activated carbon during the treatment of fish diseases, otherwise it will reduce the effect of drugs. Activated carbon used to absorb excess drugs, do not use again
