Is it some cooking class:rolleyes: nevermind Sometime i also face this problem, but i think it is due to time!! Well i will also see here again for the correct answer.

But which type of lignin do you want to dissolve??

How much is the life of activated carbon (assuming it is pure) ??

As activated carbon has all types of functional groups, then why it is not reactive?? They can play some role..

Is it possible to dissolve activated carbon in some chemicals?? and if yes then how can we test it??

Why forrmaldehyde is sold in 37% solution???

When was activated carbon discovered, like it is usually said it was discovered by Ostreijko in 1901. BUT what i want to know is that was it dscovered by Egyptians or Ancient Indus inhabitants(Aryans) or Romans. Reason of my question is that i read in books all three names but still i do not know when it was really used FIRST TIME

These days, i have seen that v. small scale/domestic water purifiers use three step water purification system, ion exchange, activated carbon adsorption and UV treatment, but YT is right that they are expensive.. Can we mix, some PAC with flocculant?

thats good, keep it up. Today i want to discuss one thing more about active carbons, do you have any idea how many wastewater treatment plants in US or other parts of world use activated carbon?? ----

I think UV light is good only for organic impurities/materials sticked on active carbons For inorganics??

I sincerely thanks YT and Ryan for keeping this topic alive and for their knowledge. Knowledge spreads by sharing so i request viewers to share their views, so that all can get benefit. Dont hesistate to ask and put views..

Dear YT, in one of your post you mentioned about regeneration of activated carbon by UV, can you pl. tell us something about that (if possible in detail) thanks

do you have any idea, how to make monoliths from powdered activated carbons and its precursors??

yeah i think it will work, but if u do some exp then do tell your exp here too

do you know os some site giving some video of activated carbon, showing their porous structures like tunnels and interlinking tunnels

but videos are not working, so pl. suggest some more sites too

Hello, i want join some forum and discussion group on activated carbons, if you know then pl. do post me some. thanks:-)

Pls suggest where to see articles related to see environment and pollution and it is not here then there is need to develop it

It is good to see your will and to note that you want to take measues, but for suggesting the measue, their type, quantity and extent of toxicity are also needed.
