If our carbon material is activated carbon, will the process be different? Is there any text we can take as reference?

I think it is not be the difference will be using activated carbon, but this classical titration method wont be produced accuracy. generally Boehm method is one used to determined the amount of impurities in terms of acid/basic funtional group present in it. i dont have references, but little known a basic tritration principle. Try this, may workout use for your studies. it may the presence of acid functional group impurities, you should go for basic tritration. In this case take your samples range 50 mg to 300 mg dissolve in 0.005 to 0.01 mole solution of HCl/H2SO4 tritrate against the equalent proportion mole of strong base NaOH/NaHCo3. You may will get greater than the equalent neutralization points in terms of milimoles. That milimoles V2 deduced to known volume of V1 acid that you added dvided by again known V1 you will get the impurities in terms of milimole. K. Take another sample for base impurities identification do that reverse oder of previous tritration procedure and you will getting subsequent impurities. This all simple strong acid vs strong base tritration method. you will using appropriate indicators within the buffer range, electronic search will identify indicator usages. all the best

Dear Haran and Nelson:
While Boehm titration is used to treat with asidic functional groups, I wonder which way is proper in titration for basic functional groups.
I think this method is suitable for determining the basic sites as well. If your looking for basic sites in regards to nitrogen, thats a whole other deal but see the link for more information.

A bit late.... But this can help somebody else.

Can please anyone help me for boehm titration....i am using back titation method and i want to know how much volume of HCl need to titrate the bases. I am geeting very less difference and even negative values also for my samples against blank. Is this ok or wrong....and whether it is necessary to record the pH also....??? and if yes then at which point.....please someone help me out for this......please....
maybe u can see this article "Application of sulfonated nanoporous carbons as
acid catalysts for Fischer esterification reactions

Hello, could be equivalent to do a direct titration of biochar using HCl to determine the surface acid sites?
can any one tell me difference between carbon black and activated carbon.thanks
