Buffer Capacities
« on: October 17, 2011, 09:00:22 AM »
Hello All,

I am currently doing a project on Anaerobic digestion. My task is to find out the buffering capacity of different buffer systems prsent in sludge i.e. carbonate, ammonium, VFA etc. Does anybody help me regarding that. As far as i found out that we can do that using simple titrations. But i don't know how or how to carry out the experiments. Does anybody know some good book on this topic or literature which can help.

Thanks in advance for help.

There is no single, generally accepted definition of the buffer capacity. Start finding out what definition are you expected to use, or which definition will be most practical in your case.

You can use the definition capacity = db/dpH Measure initial pH. Then add stranded NaOH solution and monitor pH. Use appropriate amounts.
